Zinc Selenide Optical Fibers

摘要

Semiconductor waveguide fabrication for photonics applications is usually performed in a planar geometry. However, over the past decade a new field of semiconductor-based optical fiber devices has emerged. The drawing of soft chalcogenide semiconductor glasses together with low melting point metals allows for meters-long distributed photoconductive detectors, for example. Crystalline unary semiconductors (e.g., Si, Ge) have been chemically deposited at high pressure into silica capillaries, allowing the optical and electronic properties of these materials to be exploited for applications such as all-fiber optoelectronics. In contrast to planar rib and ridge waveguides
