Abstract

Wideband optical interconnections aver short distances require significantly less optical power (i.e. < 10 microwatts) than do long-haul communication links for which most laser diodes are designed. The current trend in laser diode development emphasizes high power and single mode operation. For local point-to-point interconnections where laser power dissipation is a primary concern (e.g., systems having many channels and interconnection to super-conducting electronics), low threshold operation is paramount, while mode quality is less important. Our approach to laser design has been redirected by these requirements for low power operation. We present measurements of low-threshold laser diodes at cryogenic temperatures and discuss the suitability of such devices for low power operation with super-conducting electronics. We also discuss laser diode design approaches which emphasize micropower operation.
