Abstract
The performance of low-temperature semiconductor and superconductor devices has been shown to be superior to that of many conventional room-temperature electronic devices. In these low-temperature electronic systems, optical interconnects using semiconductor lasers are good candidates for data transmission, either within the low-temperature electronics or between the low-temperature electronics and room-temperature electronics. Low-lasing-threshold-current operation of the semiconductor lasers is required in these low-temperature applications. In addition, studying the threshold-current behavior at cryogenic temperatures provides useful information for exploiting the threshold-current limit of semiconductor lasers.
