Chalcogenide glasses (ChGs) are technologically superior materials, and their properties underpin the demands of whispering gallery mode–based integrated photonic devices. The prime focus of this review is to showcase the recent advances in the field of ChG high Q cavities. The review also covers the theoretical research aspects and brief on the research challenges and limitations involved in the topic.
Solution-processed chalcogenide glasses (ChGs) are a cost-effective and facile way of fabricating hybrid ChG-silica photonic crystal fibers (PCFs). The bulk glass preparation and the solution-processing of glass are discussed. Optimized annealing conditions are used for assessing the quality of the ChG layers inside PCF holes by using solution-processed Ge-Sb-Se glass film. Finally, the deposition of solution-based ChG layers inside the holes of PCF is demonstrated, which can be used as a platform for various sensor and all-fiber tunable device fabrication and non-linear optical (NLO) applications.
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.
