We report on the complexity comparison of the digital signal processing (DSP) module to compensate chromatic dispersion and non-linearities, i.e. digital backward propagation (DBP) algorithm. The dual-polarization quadrature phase shift keying (DP-QPSK), dual-polarization quadrature duobinary (DP-QDB) and dual-polarization quadrature amplitude modulation (DP-16QAM) encoded signals at a bit-rate of 112Gbit/s for N-channels are transmitted over 1640km fiber link. The single channel (N=1) and multi-channel (N=10) DWDM transmission performances are compared in this paper. In case of multi-channel system, 10 transmitters are multiplexed with 25GHz channel spacing. The fiber link consists of Large Aeff Pure-Silica core fiber (LA-PSCF) with 20 spans of 82km each and has the physical parameters of: α=0.16dB, D=21ps(nm-km) and γ=0.6(km-1.W-1). No in-line optical dispersion compensator is employed in the link. Erbium-doped fiber amplifiers (EDFAs) are modelled with 13.12dB of gain and 4dB of noise figure. A phase-diversity homodyne coherent receiver is used to detect the signals. To simplify our numerical analysis, we neglect the effect of polarization mode dispersion (PMD) and laser line width. The system performances are evaluated by monitoring the bit-error-ratio (BER) and the forward error correction (FEC) limit corresponds to BER of 3.8×10-3. The DBP algorithm is implemented after the coherent detection and is based on the logarithmic step-size based split-step Fourier method (L-DBP). The results depict that DP-QDB can be used to transmit 112Gbit/s signals with an spectral efficiency (SE) of 4-b/s/Hz, but at the same time has a higher tolerance to non-linear transmission impairments. By utilizing DP-QDB modulation, comparative system performance w.r.t DP-16QAM transmission can be achieved with 60% less computations and with a step-size of 205km.
我们报告了用于补偿色散和非线性的数字信号处理(DSP)模块的复杂性比较，即数字反向传播(DBP)算法。双极化正交相移键控(DP-QPSK)、双极化正交双二进制(DP-QDB)和双极化正交调幅(DP-16QAM)编码信号在1640km光纤链路上以112Gbit/s的比特率传输。本文比较了单信道(N=1)和多信道(N=10) DWDM的传输性能。在多通道系统中，10个发射机以25GHz信道间隔复用。光纤链路由大Aeff纯硅芯光纤(LA-PSCF)组成，每条光纤有20段82km，物理参数为:α=0.16dB, D=21ps(nm-km)， γ=0.6(km-1 - w -1)。该链路不采用直列色散补偿器。掺铒光纤放大器(edfa)的增益为13.12dB，噪声系数为4dB。采用相分集同差相干接收机对信号进行检测。为了简化数值分析，我们忽略了偏振模色散(PMD)和激光线宽的影响。通过监控系统的误码率(BER)来评价系统性能，前向纠错(FEC)极限对应于误码率3.8×10-3。DBP算法是在相干检测后实现的，基于对数步长的分步傅里叶方法(L-DBP)。结果表明，DP-QDB可以以4-b/s/Hz的频谱效率(SE)传输112Gbit/s的信号，同时对非线性传输损伤具有更高的容纳度。通过使用DP-QDB调制，可以实现与DP-16QAM传输相比的系统性能，计算量减少60%，步长为205km。

We design and analyze an ultracompact silicon electro-optic modulator operating at the 1550-nm wavelengths. The modulator consists of a Cu-insulator-Si hybrid plasmonic donut resonator coupled with a conventional Si channel waveguide. A voltage is applied between the ring-shaped Cu cap and the cylinder Cu contact located at the center-donut to modify the condition of the Cu-insulator-Si capacitor between depletion and accumulation, thus leading to a resonant wavelength shift of the resonator. In a modulator with 1-μm radius and 5-nm HfO2 gate oxide, numerical simulation predicts an intensity extinction ratio of >;6 dB for a voltage swing of ~3 V, a switching energy of ~50 fJ/bit, and a speed-of-response of >;50 GHz.

We fabricated the photonic metamaterial crystal structure and evaluate their photonic properties. The metamaterial photonic crystals studied here were periodic structures with two types of surface areas where two different dimension sprit ring resonators (SRR) were fabricated on each area. These two different SRR were designed to possess near but different resonance frequencies. We performed Fraunhofer diffraction measurement and reflection spectra measurement with polarized light for one dimensional (1D) and 2D photonic crystal structure. We successfully observed optical properties of the sample which reflected photonic crystal structure and sprit ring surface elements.

We have introduced a technique to grow novel optical fiber tip (OFT) which can be widely used in nano-photonics research. It takes help of capillary action and surface tension meniscus of hydrofluoric acid (HF) around the fiber during etching process to grow ultrafine OFT. The optical fiber used has different core material, which is etched at higher rate in HF compared to its cladding. The optical properties of the probe makes the tip very attractive as nano-optical tweezer, optical nanoantenna, probe for surface enhanced and tip enhanced Raman scattering (SERS and TERS) etc. The nano structure is also very effective for higher harmonic generation. To validate our claim we have explored few applications of the OFT, such as Bessel beam generation, second harmonic generation (SHG), optical tweezer and optical nanoantenna generating plasmonic hotspot.

In this paper, photodarkening effect in Ytterbium doped fiber (YDF) amplifier is experimentally investigated and analyzed. The experimental measurement on such effect is conducted on an YDF amplifier at 1064 nm wavelength emission, under both saturated and unsaturated operational regimes. Our results demonstrate that saturated operation created by higher stimulating power level is favored to mitigate the photodarkening effect as well as to enhance the amplifier's long term reliability. Such phenomenon is explained in terms of population inversion level of Ytterbium ion doped in fiber.

We report a new method to generate multiple optical traps by using phase Fresnel lens (PFL) array. We also demonstrate its applications on manipulating micro particles in experiment. In our experiment, the PFL array is formed by a spatial light modulation. The multiple beams generated by PFL array are directed into the inverted microscope and are highly focused in the focus plane of the objective. The 1.4μm polystyrene spheres are trapped in the experiment. Each of the trapped particles can be controlled by changing the position of the corresponding Fresnel zone plate in the array. Comparing with the hologram methods, which is the most popular method in generating optical trap arrays, the PFL array method has increased the trapping efficiency. Because the power of the useless zero-order light in the hologram method can be used in PFL array method. Besides, each of the trapped particles can be controlled separately in PFL array method, which makes micromanipulation more conveniently.

We propose a new wireless millimeter-wave (MMW) to lightwave (LW) signal converter using an electro-optic crystal suspended to narrow-gap-embedded patch-antennas on a low-k dielectric substrate. Wireless MMW signals can be received by the patch-antennas and converted to LW signals by use of the MMW electric field across the narrow-gap for electro-optic (EO) modulation. An aperture area of the patch-antennas is about 4 times larger than that fabricated on a high-k EO crystal only as the substrate. The MMW electric field across the narrow-gap of the proposed device also becomes 10-times stronger than that using the high-k dielectric EO substrate. Therefore, the conversion efficiency enhancement of approximately 20 dB can be obtained using the proposed device. It is compact, passive, and operated with extremely low MMW distortion in high-speed radio-over fiber communication and measurement systems.

We report an optical twisting alert sensor using beat frequency from a short cavity polarization-maintaining erbium-doped fiber (PM-EDF) based distributed Bragg reflector (DBR) laser. A DBR fiber laser with an effective cavity length of ~1 cm formed by a pair of fiber Bragg gratings (FBGs) inscribed on a portion of PM-EDF was developed for demonstrated. This fiber laser exhibited stable operation in dual-polarization single-longitudinal-mode. The amplitude of the beat frequency generated by two orthogonal polarizations of the cavity is twist dependence. It is shown that the beat frequency signal can be completely “turned off” at ~180° twist angle. This type of single mode DBR fiber laser can be used as optical twisting alert sensors for remotely interrogated systems and multi-parameter monitoring systems.

We present a new model for dynamically provisioning sliding bulk transfer requests in data-intensive applications over wavelength-division multiplexing (WDM) optical networks. This model can provide more flexibility for the users and serve them better. It allows the users not only to specify the sizes of submitted bulk files, but also to make decisions on the minimum bandwidth guarantee (MBG) and the time redundancy (TR) of the sliding window. We formulate the problem into two sub-problems (time scheduling, routing-wavelength assignment (RWA) and bandwidth allocation (BA)) and prove it to be NP-complete. We propose a buffer-based provisioning (B2P) architecture to deal with the problem. The approach first temporarily buffers those blocked requests at their arrival times and then attempt to provision these requests later once new resources become available. The effectiveness and the feasibility of the proposed approach are demonstrated by the simulations.
