We demonstrate chalcogenide optical fiber couplers designed with a transmission spectrum response that varies with input power. The measured critical power is as low as 126 W at a wavelength of 1938 nm.
We demonstrate chalcogenide optical fiber couplers designed with a transmission spectrum response that depends on the input power. The measured switching power is as low as 126 W at a wavelength of 1938 nm.
We demonstrate single-mode ZBLAN optical fiber couplers. A controlled tapering procedure leads to coupling ratios of 5%/95% and 14%/86% at a wavelength of 2200 nm, with insertion losses of 1.6 dB and 1.8 dB, respectively.
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.
