摘要

我们提出了一种采用单片集成锥形InGaAs-AlGaAs SQW放大器和光栅耦合器的无透镜可调谐外腔激光器(TECL)，该激光器可以在不再生的情况下制造并发出准直输出光束。我们展示了一个良好的准直输出光束和宽范围调谐的新型TECL。

Tunable external-cavity semiconductor laser using monolithically integrated tapered amplifier and grating coupler for collimating

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.
