WebRefractive index (RI) sensors are of importance in many applications since many physical, biochemical, and environmental parameters can be detected by examining RI variations. In this paper, we describe an intensity-modulated RI sensor using a bismuth telluride (Bi2Te3)–integrated tilted fiber Bragg grating (TFBG) configuration. WebThe band gap of LiZnX (X = N, P & As) is 1.91 eV, 2.04 eV and 1.51 eV correspondingly; which is in best agreement with available theoretical and experimental statistics. The optical parameters for example, dielectric constant, refractive index, optical conductivity, reflectivity and absorption parameter have been computed. fortnite without signing in or logging in
