Investigation on Full Duplex WDM Hybrid Sensor to Measure the Strain

Abstract

Abstract The effect of nano-hybrid sensor based on a wavelength division multiplexed technique (WDM) is studied using photonics crystal fiber and fiber Bragg grating (FBG). The full duplex scheme is used in the proposed system to receive and transmit the data at the same time for fast processing. The finite difference time domain photonics simulation software (FDTD) is used to observed variation in reflection and the transmission power spectra of the photonic gratings. Using line defects we created two linear waveguides, further, it is used as an optical sensor. From this work, we recommend that the proposed system can be used as in communication field for data transmission and also used in sensing application to sense the property and deformation of the object.
