Abstract :
A compact, robust, and portable fiber-coupled THz photoconductive antenna module is described. A new technique is used to focus the output light of the fiber on the chip and fix the fiber in place to provide rugged packaging. THz measurements in pulse mode confirm the performance of this module. The fiber coupled unit is very versatile and can be used in both time domain and frequency domain THz systems. A multi-quantum well InGaAs/InAlAs material is used as the photoconductive material.
