Abstract

Ten-unit individually addressable arrays of constricted double heterojunction large-optical-cavity (CDH-LOC) diode lasers have been realized by one-step liquid phase epitaxy over channeled substrates, and by bonding to ten-electrode BeO submounts. Maximum overall powers of 320 mW in cw operation and 3.6 W in pulsed operation (100 ns, 1 kHz) have been achieved. Device interspacing is 150 μm and thermal crosstalk is of little significance. The devices’ lasing thresholds, near-field patterns, and power capabilities are highly uniform across the array. This is the first report of a monolithic diode laser array capable of use in multichannel optical recording.
