A Reliable Package For Hermetic Encapsulation Of Ingaasp Edge Emitting Leds

A reliable package for edge emitting LEDs has been developed, and the assembly and characteristics are described. This package is easily fabricated, hermetic, and provides excellent coupling stability between the chip and single mode fiber. A minimum of 7,447 of coupled power into single mode fiber is typically achieved, and long-term aging indicates less than 1dB change in light output after 2000 hrs at 90°C.
