Active fail-safe terminal for fiber-optic data bus

Abstract

A novel send/receive terminal for multimode fiber bussing has been constructed in an 85‐μm‐thick LiTaO₃ plate forming a curved focusing reflector on the plate end. The low‐loss T terminal is an electro‐optic switch that requires no light source of its own. It provides maximum optical throughput in the absence of electrical excitation.
