Abstract

We present a lensless tunable external-cavity laser (TECL) using monolithically integrated tapered InGaAs-AlGaAs SQW amplifier and grating coupler, which can be fabricated without regrowth and emits a collimated output beam. We demonstrate a well-collimated output beam and wide-range tuning of the novel TECL.
