Chromatic Dispersion Compensation in Optical Fiber Communication System using FBG and EDFA
Abstract: AbstractNowadays optical communication is a most significant technique to transmit the data. In daily life we share our useful data by using optical network but dispersion is the main factor towards limiting the performance of optical system. However, the compensation of dispersion by Dispersion Compensating Fiber (DCF) and Fiber Bragg Grating (FBG) can boost significantly the system. This proposed work investigates and analyze the chromatic dispersion compensation in optical fiber …

Micro-cantilever Sensors for Efficient Gas Sensing
Abstract: AbstractMicro-cantilever has been progressively used for the development of miniaturized sensors for gas sensing, biochemical analysis, medical applications and quality and process control. Micro-cantilevers are fabricated with rectangular silicon slabs having thickness below 1 µm. For gas sensing applications, Si cantilever surface is modified with appropriate sensing materials for selective adsorption of gas/vapor or biomolecules. The bending of the cantilever due to different surface conditions is measured with laser beam …

Errors-in-Variables Model for Photovoltaic Cell
Abstract: AbstractThe contribution of solar energy to the world's total energy supply has grown significantly. Energy from the sun is the most abundant and freely available energy on the planet. So, the importance of modelling the photovoltaic cell also increased remarkably. Many models for photovoltaic cell had been proposed since the beginning of the solar energy exploitation. Electronic equivalent circuit models, first-principles models and empirical models are the different modelling techniques …
