我们制作了一个胶囊形的金属包层波长级的InP/InGaAs腔，并展示了室温下在脉冲光泵浦下的波长为1550 nm的激光输出。通过在传统矩形金属包层激光器的侧壁上引入一个优化的曲率，我们有效地降低了横电模的金属损耗，并在实验上证实了侧模抑制比和斜率效率的明显改善。
We fabricate a capsule-shaped metal-clad wavelength-scale InP/InGaAs cavity and demonstrate room-temperature lasing at a wavelength of ∼1550 nm under pulsed optical pumping. By introducing an optimized curvature to the sidewalls of a conventional rectangular metal-clad laser, we effectively reduce the metallic loss of the transverse-electric mode and experimentally confirm a clear improvement in the side mode suppression ratio and slope efficiency.
