Numerical dispersion of the time domain beam propagation method (TD-BPM) using recursive convolution is assessed through the solution of wave equation in a Debye medium. The implicit and recursive technique is compared with other existing similar techniques, such as recursive finite difference time domain (FDTD) and TD-BPM using auxiliary differential equation (ADE). An empirical relation is established so that the inherently generated dispersion can be superseded. The outstanding feature of the technique includes avoidance of a large matrix inversion with high stability for multi-pole Debye medium even at large time steps and relaxed mesh-grid.

A systematic study on the characteristics of a Mach-Zehnder interferometer based on down-tapered fiber under confined heating is presented. The effect of confined heating to this structure is also compared to distributed heating over the entire structure. The study unveils, for the first time, that only change in peak power of the transmission spectrum is observed during confined heating at the taper waist, with a sensitivity of 0.0216 dB/°C at peak wavelength of 1558.28 nm, whereas the distributed heating over the entire structure causes wavelength shift with a sensitivity of 0.053 nm/°C for the observed peak at initial wavelength of 1557.476 nm. These distinct responses can be exploited as a new approach for spectrum shaping and multi-parameter sensing.

In this study, a split ring resonator (SRR) design is simulated for the detection of different cancer cells in biosensing application using COMSOL Multiphysics software. Finite element method (FEM) is used to evaluate electric field distribution in SRR. The analysis of biosensor is done in microwave region. Small change in dielectric constant produces shift in resonant peak of SRR so this biosensor can be used for the detection of different types of cancer cells like Hela, PC12, MDA-MB-231, MCF-7, Jurkat. The advantages of this biosensor are low cost manufacturing and level free sensing with appropriate sensitivity.

In this paper, an ultraviolet (UV) sensor based on optical sensing is presented. The center region of the fiber optic is covered with dyes or UV markers. Two configurations of sensors were fabricated which are based on fluorescent brightener and mercury dyes doped. The effect on the sensitivity and linearity of differences in length and illumination intensity were observed. For this experiment, 1000μm diameter of plastic optical fiber (POF), UVA (365nm) and UVC (265nm) as the UV sources were used. Meanwhile, for the light source, Deuterium and Halogen was applied. To obtain the result, one end of the fiber was connected to the light source and another one was to a spectrometer and the dyes were exposed to UV source as to observe the emission spectra. As a result, the fluorescent emission obtained for the sensors doped with Fluorescent Brightener and mercury were at 500nm and 600nm wavelengths respectively. In summary, the 6cm unclad fiber which is coated with fluorescent brightener and exposed to UVA is the most suitable since it shows the best characteristics.

This paper demonstrates an optical fiber proximity sensor for micro distance measurement. The optical fiber was used to detect a silver plate which acted as an obstacle. A flat end of a standard single mode optical fiber was functioned to emit the broadband light at near infrared wavelength region and receive the reflected light from the obstacle. The distance between the optical fiber and the obstacle was varied from $0mu mathrm{m}$ to 400 $mu mathrm{m}$. We experimentally characterized the sensor sensitivity based on their free spectral range. The optical fiber tip has shown its potential for proximity sensing application with sensitivity value of 0.0199 $mathrm{nm}/mumathrm{m}$ and regression value up to 0.9126.

We experimentally demonstrate the transmission performance of a high-throughput OXC architecture that utilizes recently proposed spatially-jointed flexible waveband routing. Its feasibility is experimentally verified using 64-channel 400-Gbps dual-carrier DP-16QAM signals aligned with 75 GHz spacing in 4.8 THz of the full C-band. Our OXC design is shown to attain the net OXC throughput of 2.15 Pbps, OXC port count of 84, hop count of 7, and transmission distance of 700 km.

This paper demonstrates a Mach-Zehnder interferometer (MZI) with enhanced strain sensitivity. Strain sensitivity enhancement is achieved by encapsulating the MZI with off-axis coating. Experiments comparing the off-axis with on-axis encapsulation reveals that the enhancement achieved is at least tenfold. Effect of various types of elastic coating is also investigated. The results show that softer coating with give a higher strain sensitivity. This technique offers a simple packaging to enhance any discrete fiber optic sensor.

Indonesia is the third world's largest rice producer, which has wide variety of types and qualities of rice. Based on SNI 6128:2015, rice quality can be classified based on the form, colour and moisture content of the rice grain. On the other hand, rice is consumed to fulfill the nutritional needs of the body. So, it is important to know the type of rice which provide best nutrient content. In this paper, we report preliminary research to predictively determine the quality of rice based on amylose phenolic and flavonoid content measured using FTIR Spectroscopy technique. Chemical analysis method was used as a validation to this developed predictive system. Partial Least Square (PLS) were used to determine the levels of amylose, phenolic, and flavonoids of rice and the Principal Component Analysis (PCA) methods for clustering the types and quality of rices. Results showed that the coefficient of determination of the proposed prediction system of amylose content, phenolic and flavonoids were 0.95; 0.86; 0.95, respectively, with respective RMSE value were 1.4; 0.72; 0.44. Using this technique, rice samples used can be classified into three class of quality, i.e, high quality, premium quality, and the medium quality rice.

Optical cavity supporting enhanced surface plasmon polariton (SPP) is demonstrated with the incorporation of a high-Q whispering-gallery mode (WGM) microbottle resonator (MBR). The thin gold metal-film deposited on the MBR only covers half of the resonator surface with a meniscus profile and maximum thickness of 200 nm. Composite TE (TM) Q-factor value in the range of 1900 (2000) was calculated with highly discriminated polarized light coupled into the hybrid microcavity.
