We adapted the traditional FFT-BPM to assess the performance of plasmonic waveguide as biosensor. The tightly confined optical power in such waveguide enables an efficient way to detect tiny changes in the composition of material properties adjacent to the metallic boundary of the plasmonic waveguide. Although Kretschmann configuration has been adopted by several authors, its performance evaluation by the FFT BPM is presented here for the first time to the best of our knowledge. A surface plasmon biosensor based on Kretschmann configuration is studied by this modified FFT-BPM to detect the mosquito-borne dengue virus in the blood.
我们采用传统的FFT-BPM来评估等离子波导作为生物传感器的性能。这种波导的光功率受到严格限制,因此可以有效地检测等离子体波导金属边界附近材料性质组成的微小变化。尽管Kretschmann配置已被多位作者采用,但据我们所知,本文还是第一次介绍FFT BPM对其性能的评估。采用改进的FFT-BPM,研究了一种基于Kretschmann结构的表面等离子体生物传感器,用于检测血液中蚊媒登革热病毒。

Copper-based cables have limitation of distributing power safely and efficiently for Internet of Things (IoTs) application as well as during emergency conditions. This research paper aims to demonstrate the power over fiber (PoF) distribution system network in the short-haul distance, as an alternative to copper-based cable. The maximum efficiency obtained for the full system was 12% at 450 mA of laser driving current. The obtained results clearly demonstrated that as the laser driving current increases from 50 mA to 450 mA, overall efficiency of the system increases. The prototype was designed with a low power output where the main parameter that affects the overall efficiency system is the optical to electrical conversion module. Prototype results demonstrated the potential of PoF for low power distribution system.

An optical fiber tip sensing probe coated with graphene is proposed for nitrate-sensing application. The sensor was coated with graphene using dip-casting method to detect nitrate at different concentrations ranging from 0 to 50 ppm. The graphene-coated fiber tip sensor was highly sensitive in detecting nitrate ion. When the concentration of the nitrate solution was dropped onto the sensing region, the reflected optical power decreased as the nitrate concentration increased. Without the graphene layer, the uncoated fiber tip sensor only had a sensitivity of 0.0076 dBm/ppm. However, the coated sensor's sensitivity was significantly enhanced to 0.0624 dBm/ppm, eight times higher than the uncoated fiber tip sensor, mainly due to the adsorption of nitrate on the graphene surface. This graphene-coated optical fiber tip sensor has a high potential to be used in nitrate-sensing applications.
提出了一种涂覆石墨烯的光纤尖端传感探头,用于硝酸盐传感。该传感器采用浸铸法涂覆石墨烯,以检测0 ~ 50 ppm不同浓度的硝酸盐。石墨烯涂层光纤尖端传感器对硝酸盐离子的检测具有很高的灵敏度。当硝酸溶液的浓度降至传感区域时,反射光功率随硝酸浓度的增加而降低。没有石墨烯层,未涂覆的光纤尖端传感器的灵敏度仅为0.0076 dBm/ppm。然而,涂层光纤传感器的灵敏度显著提高至0.0624 dBm/ppm,是未涂层光纤传感器的8倍,这主要是由于硝酸盐在石墨烯表面的吸附。这种石墨烯涂层光纤尖端传感器在硝酸盐传感方面具有很大的应用潜力。

Passive Optical Network (PON) has evolved drastically in order to provide greater speed and better reliability such as Next Generation PON1 (NG-PON1) and NG-PON2 which able to provide more than 40 Gbps and 128 Gbps of bandwidth respectively. Due to rapid growth of PON technologies, researchers have conducted many thorough experiments in order to enhance current PON-base technologies in a form of testbeds. However, most of the studies show that the testbeds have limitations either on its configurability, compactness or cost-efficiency. Hence, this motivates us to propose a lab-scale router testbed in PON architecture by using Raspberry Pi for its promising features and size. The experiments were done in a lab-scale area because the proposed router testbed is to provide a proof-of-concept solution of a reconfigurability router in PON. The results of the experiments are in terms of throughput, end-to-end delay and jitter for both downstream and upstream transmissions. After conducting the experiments, we have come to a conclusion that Raspberry Pis are suitable to be used as lab-scale routers in fiber networking architectures due to their reconfigurability, open source kernel, space-friendly and cost-efficient.
无源光网络(PON)为了提供更快的速度和更好的可靠性而急剧发展,例如下一代PON1 (NG-PON1)和NG-PON2,它们分别能够提供超过40 Gbps和128 Gbps的带宽。由于PON技术的快速发展,研究人员进行了许多深入的实验,以便以试验台的形式增强现有的PON基础技术。然而,大多数研究表明,试验台在可配置性、紧凑性或成本效益方面存在局限性。因此,这促使我们在PON架构中提出一个实验室规模的路由器测试平台,利用树莓派的有前途的特性和尺寸。实验是在实验室规模的区域进行的,因为所提出的路由器测试平台是为了提供PON中可重构路由器的概念验证解决方案。实验结果是在吞吐量,端到端延迟和抖动对下游和上游传输。经过实验,我们得出结论,树莓派适合用作光纤网络架构中的实验室规模路由器,因为它们具有可重构性,开源内核,空间友好和成本效益。

This paper presents a model for 2D simulation of silicon optical PN phase shifter which can be used for design, optimization, and parametric study of the phase shifter. The model uses the effective index method for modal analysis and takes into account the 2D depletion width across the waveguide to model the PN junction diode. The developed 2D model shows good agreement with numerical TCAD simulation. The model accurately simulates a PN optical phase shifter with variable input parameters viz. wavelength, waveguide dimensions, doping concentrations, PN junction offset, and calculates the phase shift, modulation efficiency, absorption loss, and insertion loss.

Simulation of a Simple Scheme to Generate Flat Frequency Comb Using Cascaded Single-Drive Mach-Zehnder Modulators 利用级联单驱动马赫-曾德调制器产生平坦频率梳的简单方案的仿真

A scheme to generate flat optical frequency comb using two cascaded Mach-Zehnder modulators (MZMs) is proposed and demonstrated through simulation. By adjusting the amplitude of the modulation signal and the DC voltage supplied to the modulators, 7 comb lines with 1.15 dB flatness can be generated. An ideal 1×2 electrical splitter is used to split the RF (radio frequency) modulation signal ideally, so that both modulators are supplied with the same amplitude and frequency. In case using 90° hybrid coupler as a splitter, both modulators received different frequencies due to the 90-degree phase shift and the output was 3 and 5 comb lines with a corresponding flatness of 0.31 dB and 3 dB, respectively. Biasing was at the quadrature point to achieve linear modulation and avoid output optical distortion from the nonlinear region of MZM transfer function. The scheme is simple and cost-effective using only one signal generator, and it can be used mostly for analog optical links applications.
提出了一种利用两个级联马赫-曾德尔调制器(MZMs)产生平面光频梳的方案,并通过仿真进行了验证。通过调节调制信号的幅值和提供给调制器的直流电压,可以产生7条平坦度为1.15 dB的梳状线。一个理想的1×2电分离器用于理想地分割RF(射频)调制信号,以便两个调制器提供相同的幅度和频率。在使用90°混合耦合器作为分频器的情况下,由于90度相移,两个调制器接收到不同的频率,输出分别为3梳线和5梳线,对应的平坦度分别为0.31 dB和3 dB。在正交点进行偏置,实现线性调制,避免了MZM传递函数非线性区域产生的输出光畸变。该方案简单、经济,仅使用一个信号发生器,可用于模拟光链路应用。

The experimental setup of the lensless microscopic imaging system and the reconstruction algorithms of angle spectrum method was introduced. Comparing the resolution of the USAF resolution plate image, the amplitude image resolution acquired by the angle spectrum method is up to 3.1 $mu mathrm{m}$ and proves this method is good reconstruction algorithm of single-frame lensless microscope imaging. Results show that the lensless imaging field of view is 4.4 times than that of a 5X microscope, and its resolution is between 5X and 10X optical microscopes.

Photoluminescence (PL) and Raman studies were carried out to investigate the effect of growth rate on $mathrm{GaAs}_{1-mathrm{x}}mathrm{sBi}_{mathrm{x}}$ alloys. The samples were grown between 0.09 and 0.5 $mumathrm{m}/mathrm{hour}$, At room temperature, the lowest PL peak energy (1.07 eV) was obtained by sample grown at 0.23 $mumathrm{m}/mathrm{hour}$. Samples grown at lower and higher than 0.23 $mumathrm{m}/mathrm{hour}$ showed PL peak energy redshift and blueshift, respectively. Raman data show peaks at 162, 228, 270 and 295 cm−1which correspond to the GaAs like phonons. The GaBi like phonons were also observed at 183 and 213 cm−1but their intensity are significantly weaker compared to GaAs like phonons. PL and Raman data show that Bi incorporation into GaAs lattice is dependent on the growth rate and in this study, the highest Bi concentration was obtained for sample grown at 0.23 $mu mathrm{m}/mathrm{hour}$.
采用光致发光(PL)和拉曼光谱研究了生长速率对$ mathm {GaAs}_{1- mathm {x}} mathm {sBi} { mathm {x}}$合金的影响。样品生长在0.09 ~ 0.5 $mumathrm{m}/mathrm{hour}$,在室温下,生长在0.23 $mumathrm{m}/mathrm{hour}$的样品获得了最低的PL峰值能量(1.07 eV)。在低于和高于0.23 $mumathrm{m}/mathrm{hour}$时生长的样品分别出现了PL峰值能量红移和蓝移。拉曼数据显示在162、228、270和295 cm−1处的峰值对应于类砷化镓声子。在183和213 cm−1处也观察到类GaBi声子,但其强度明显弱于类GaAs声子。PL和Raman数据表明,Bi在GaAs晶格中的掺入取决于生长速率,在本研究中,在0.23 $mu mathm {m}/ mathm {hour}$生长的样品中获得了最高的Bi浓度。

Graphene has a zero-band gap structure with pho-todetection from visible to terahertz frequencies. Graphene also has high carrier mobility, making it suitable for optoelectronic applications. Lithium niobate is a polar crystal with a high pyroelectric coefficient. The laser absorbed by lithium niobate is converted into heat, and the change in temperature causes spontaneous polarization of the lithium niobate. The lithium niobate pyroelectric polarization induces the surface free electric charge to enter the graphene, and changes the Fermi level of the graphene, thereby improving the photoelectric performance of the device. In this work, the photodetector shows a responsivity of $sim 2.12times 10^{6}mathrm{A}/mathrm{W}$ at 22pw incident power, high detectivity of 6.29 $times 10^{14}$ Jones and wide detection rang from visible to near infrared. Particularly, the high rise/decay speed of 20ms/30ms is achieved. This work suggests that the lithium niobate has great potential for high-performance photodetectors.
石墨烯具有零带隙结构,具有可见光到太赫兹频率的光探测。石墨烯还具有高载流子迁移率,使其适合光电应用。铌酸锂是一种具有高热释电系数的极性晶体。被铌酸锂吸收的激光转化为热量,温度的变化引起铌酸锂自发极化。铌酸锂热释电极化诱导表面自由电荷进入石墨烯,改变石墨烯的费米能级,从而提高器件的光电性能。在这项工作中,光电探测器在22pw入射功率下的响应率为2.12 × 10^{6} mathm {a}/ mathm {W}$,探测率为6.29 × 10^{14}$ Jones,探测范围从可见光到近红外都很宽。特别是,实现了20ms/30ms的高上升/衰减速度。这项工作表明,铌酸锂在高性能光电探测器方面具有很大的潜力。

In this paper, the use of laser feedback interferometer to detect the minute displacement of low frequency vibration from a piezo actuator and acoustics wave detection from a standard speaker are presented. The preliminary results of time domain and its corresponding FFT graphs are illustrated. The acoustics signal is further investigated by varying the distance of the speaker with the laser feedback interferometer optical path. The results show that measurement of vibration as low as 5 Hz and the detection of acoustics wave are achievable.
