Fiber-coupled transceiver for terahertz reflection measurements with a 4.5  THz bandwidth

Abstract

We present a fiber-coupled transceiver for THz time-domain spectroscopy, which combines an emitter and a receiver on a single photoconductive chip. With a bandwidth of 4.5 THz and a peak dynamic range larger than 70 dB, it allows for THz reflection measurements under normal incidence. This THz reflection head is a promising device for applications in such fields as material inspection and nondestructive testing.
