A GaAs laser array multispot source has been fabricated in which the array is bonded to a silicon substrate, which also contains an accurately aligned collimating lens and an array of fiber lightguides. The coupling efficiency of each laser to its corresponding lightguide is greater than 50%. The package is cooled by a thermoelectric cooler, allowing cw, room-temperature operation of the array at 5 mW output per fiber. This source is useful for multichannel optical-communication applications. © 1977 (publisher). All right reserved.
