| 摘 要： | 半导体纳米激光的研究是目前纳米技术（或纳米光子学）和半导体激光交汇产生的研究前沿。本文将综述这一领域最近一些最激动人心的进展。我们将集中讨论两种半导体纳米结构的纳米激光：自下而上生长而成的纳米线和自上而下刻蚀制成的纳米柱状结构。本文将综述这些纳米激光器的特殊特征，特别是利用表面等离子效应而成制成的金属{半导体等离子体激光，即目前世界上最小激光器的最新进展。由于这些纳米激光器的微小的尺寸以及对光在空间限制增强，我们必须重新检验半导体激光器中某些熟悉的概念在纳米尺度上的正确性和含义，例如模式增益和光限制因子（CF）的概念。本文将从统一的观点解释光限制因子在电介质和等离子体纳米激光器中的某些似乎反常的行为。在本文的通篇论述中，我们将尝试回答究竟激光器的尺寸能够小到什么程度，或者激光器的尺寸是否存在一个最小极限等基本问题。

| Abstract: | Semiconductor nanolasers represent the current frontier of research in the confluencing area of nanotechnology(or nanophotonics) and semiconductor lasers.In this paper,we review some of the most exciting progress made recently in the area.We will focus on nanoscale lasers made of semiconductor nanowires grown in a bottom-up fashion or nanopillars that are produced through a top-down wafer etching.Special features of these nanolasers will be reviewed.In particular,recent results on metal–semiconductor plasmonic lasers will be presented which represents the smallest lasers by taking advantages of surface plasmonic effects.Due to the small size and strong confinement in these nanolasers,certain familiar concepts in semiconductor-laser physics need to be re-examined to determine their validity or implication at nanoscale.These include the concept ofmodal gain and confinement factor(CF).The seemly abnormal behavior of CF in dielectric and plasmonic nanolasers will be explained from a unified point of view.Throughout this tutorial,we attempt to address the question of how small a laser can be made or whether there exists an ultimate size limit for a laser.Laser intensity profile along a nanowire laser.The nanowire laser is confined to the left by the substrate and surrounded by air from all other sides. |
