Lasers based on microcavities are extremely attractive for their compactness, low power dissipation, and potential for ultrafast modulation speed. We describe an ultrasmall laser based on a subwavelength electronic inductor-capacitor (LC) resonant circuit that allows for extreme confinement of the electric field. This electrically injected laser operates at a frequency of 1.5 terahertz, and the mode volume is strongly subwavelength. The design concept of the LC resonator can be extended from the terahertz range to higher frequencies and also applied to detectors and modulators.
基于微腔的激光器具有结构紧凑、功耗低和超快调制速度等优势，极具吸引力。我们描述了一种基于亚波长电感器-电容器 (LC) 谐振电路的超小型激光器，它可以实现对电场的极限约束。这种电注入激光器的工作频率为 1.5 太赫兹，模式体积远小于波长。LC 谐振器的设计理念可以从太赫兹扩展到更高的频率，并应用于探测器和调制器。
