In this paper, comparative analysis of code performance of dissimilar optical 2-D codes from Optical Orthogonal code family has been studied. Optical 2-D codes considered from OOC family are (n,w,1,2) OOC, SPS/OOC, OCFHC/OOC, EPC/OCS and VWOOC. By utilizing hard limiting error probability (HEP) equations and combinatorial method, code performance of each considered code is evaluated in detail. On the basis of detailed comparative performance analysis, EPC/OCS is concluded as best performing codes among all other optical codes under consideration. EPC/OCS possesses much better correlation properties, along with lower hit probability values which are responsible for its supremacy in performance characteristics to the other OOCs considered.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
