A spiral shaped plastic optical fiber (POF) has been constructed and applied for sensing of the refractive index a sucrose solution. The mechanism is based on evanescent wave interaction between light travelling within medium surrounding it. Difference in output voltage observed as concentration solution varied from 10% to 50%, demonstrating uniform relation among them. By varying pitch shape applying strain same, sensitivity POF refined. This spiral-shaped sensor comparatively easy...
Abstract This current work focuses on the study of residual stress introduced in thin surface micromachined films due to thermal stress. A model is presented here change as temperature changes and turn how this affects resonant frequency resonator. The uses two design; a resonator with straight folded cantilevers. also involves analysing performance material properties are changed. analyses done Nitinol which Shape Memory Alloy (SMA). simulation carried out COMSOL Multiphysics.
Photonics technology has the potential for applications in space environment which is helpful studying and analyzing various parameters of space. This integration photonics called Astrophotonics. Various types Specialty Optical Fibers (SOF) have been designed specific applications. The SOFs capacity to sense high temperature as well a wide range radiation. These fibers are enabled multi-point real-time monitoring radiation parameters. We proposed implementation such specialty optical sensors...
The analysis of band structure one-dimensional (1-D) photonic crystal containing dispersive and non-linear materials has been presented. spectra for the different combination crystals have calculated by well-known plane wave expansion method. effect on structures determined. third-order nonlinearity considered in material, Lorentz–Drude model taken material. gaps are affected presence material like gold. We observed that normalized frequency difference between bands decreases increasing...
