摘要

提出了一种集成布拉格反射镜的光导太赫兹(THz)发射极。相对于没有反射镜的发射体，该发射体的发射效率提高了10倍。此外，我们首次演示了频率高达100khz的太赫兹输出辐射的电调制。

Photoconductive terahertz emitter with an integrated semiconductor Bragg mirror

A photoconductive terahertz (THz) emitter with an integrated Bragg mirror is presented. The emitter exhibits improved emission efficiency by a factor of 10 with respect to an emitter without a mirror. In addition, we demonstrate for the first time the electrical modulation of the THz output radiation with frequencies up to 100 kHz.
