Hermetically Sealed High Radiance LEDs for Fibre Optic Communications

摘要

This report describes the development of hermetically sealed pigtailed LEDs for Fibre Optic Communications. Hermeticity to MIL STD 7503, 1017 is achieved by a fibre metallisation/solder method, high efficiency and speed (3 nanosecs typical) by optimised GaAs-GaA1As proton isolated junction, and high output power by microlens coupling (800 micron w typical in a 100 micrometers core diameter 0.3NA pigtail).
