The results of computer simulation of optical properties of one-dimensional (1D) photonic crystal with defect, based on semiconductor-dielectric layers are presented. As semiconductor silicon and germanium were used. The influence of temperature on spectral position of defect transmission band was studied. It was shown that for photonic crystal based on silicon temperature sensitivity is 0.07 nm/K and 2.6 dB/K. For photonic crystal based on germanium – 0.37 nm/K and 7.8 dB/K. This makes such photonic crystals promising for use in temperature sensors as sensitive element.
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.
