Abstract

Standard Michelson interferometers generally make use of narrowband, continuous-wave light as their longer coherence lengths make interference easier to ascertain. In contrast, for broadband, pulsed light, whose coherence lengths lie in the micrometer range, proving interference is a greater challenge. Using terahertz time-domain spectroscopy, this paper experimentally demonstrates interference for far-infrared, broadband (50-1000 GHz), ultrashort (∼50ps) light pulses with, at most, a 6.66% error based on calculations and the central frequency.
