Abstract

A fiber-assembled CW THz System operating at 1.5 microm is presented. High speed telecom photodiodes integrated with planar THz antennas serve as THz emitters with power up to 10 microW. Photoconductive antennas based on LT InGaAs/InAlAs multi-layer structures allow coherent detection. The system operates in a wide frequency range of 0.1 -1.6 THz.

摘要

介绍了一种工作在1.5微米波长的光纤组装连续波太赫兹系统。与平面太赫兹天线集成的高速电信光电二极管用作功率高达10微瓦的太赫兹发射器。基于LT InGaAs/InAlAs多层结构的光电导天线可实现相干探测。该系统在0.1 - 1.6太赫兹的宽频率范围内运行。
