Abstract

We propose and report on a method that demultiplexes multiple carrier channels directly in the terahertz (THz)-domain by utilizing a THz-wave asymmetric Mach-Zehnder interferometer (AMZI). The frequency division multiplexing (FDM) channels can be demultiplexed with the AMZI. As preliminary investigation, we fabricated the AMZI by employing THz-wave bulk components including beam splitters, mirrors, and lenses. We show demultiplexed results of a two channel FDM on-off keying signal in the 300 GHz band, which was produced by utilizing a high-speed photo-mixing, with the AMZI.
