我们报道了一种电驱动、单模、低阈值电流(类似于260微安)光子带隙激光器在室温下的实验演示。电流脉冲通过位于模式中心的亚微米大小的半导体线注入，品质因数降级最小。实际感兴趣的模式以非简并的单极模式运行，通过测量与基于实际制造的结构参数的计算的比较证明了这一点。作为迈向无阈值激光器或单光子源的一小步，这种波长大小的光子晶体激光器可能会引起光子晶体、腔量子电动力学和量子信息界的兴趣。
We report the experimental demonstration of an electrically driven, single-mode, low threshold current (similar to260 muA) photonic band gap laser operating at room temperature. The electrical current pulse is injected through a sub-micrometer-sized semiconductor wire at the center of the mode with minimal degradation of the quality factor. The actual mode of interest operates in a nondegenerate monopole mode, as evidenced through the comparison of the measurement with the computation based on the actual fabricated structural parameters. As a small step toward a thresholdless laser or a single photon source, this wavelength-size photonic crystal laser may be of interest to photonic crystals, cavity quantum electrodynamics, and quantum information communities.
