Abstract

Site-controlled quantum-wire photonic-crystal microcavity laser is experimentally demonstrated using optical pumping. The single-mode lasing and threshold are established based on the transient laser response, linewidth narrowing, and the details of the non-linear power input-output characteristics. Average-power threshold as low as approximately 240 nW (absorbed power) and spontaneous emission coupling coefficient beta approximately 0.3 are derived.

摘要

通过光泵浦实验证明了位点控制的量子线光子晶体微腔激光器。基于瞬态激光响应、线宽变窄以及非线性功率输入-输出特性的细节，确定了单模激光发射和阈值。得出平均功率阈值低至约240 nW（吸收功率），自发发射耦合系数β约为0.3。
