传统的半导体激光器由于受到光反馈系统的限制而受到衍射极限的限制。因此，激光器的尺度不能小型化，因为它们的空腔不能小于激光波长的一半。然而，基于表面等离子激元（SPPs）的激光器可以在深亚波长，甚至纳米尺度上工作。此外，现代纳米制造技术的发展为微级甚至纳米级激光器的制造提供了条件。本文综述了近年来基于SPPs的纳米激光器的研究进展。介绍了SPPs的基本原理，给出了几种纳米级激光器的结构和特性。指出当前纳米级激光器存在的主要缺陷是极化子损耗高、制造和电子抽运技术困难。最后，对基于SPPs的纳米级激光器的研究和应用前景进行了展望。
Conventional semiconductor lasers suffer from the scale of the diffraction limit due to the light to be confined by the optical feedback systems.Therefore,the scales of the lasers cannot be miniaturized because their cavities cannot be less than the half of the lasing wavelength.However,lasers based on the Surface Plasmon Polaritons(SPPs) can operate at a deep sub-wavelength,even nanometer scale.Moreover,the development of modern nanofabrication techniques provides the fabrication conditions for micro-or even nanometer scale lasers.This paper reviews the progress in nano-lasers based on SPPs that have been demonstrated recently.It describes the basic principles of the SPPs and gives structures and characteristics for several kinds of nanometer scale lasers.Then,it points out that the major defects of the nanometer scale lasers currently are focused on higher polariton losses and the difficulties in fabrication and electronic pumping technologies mentioned above.Finally,the paper considers the research and application prospects of the nanometer scale lasers based on the SPPs.
