Abstract

A photonic sub-terahertz wave generation technique that utilizes an optical comb generator, a J-band UTC-PD module as a photomixer, and commercial optical components such as arrayed waveguide gratings (AWGs), optical switch units (OSWs), and couplers is presented. The proposed scheme offers broadband frequency tunability with high spectral resolution, high signal purity, and narrow linewidth. The proposed photonic sub-terahertz wave generator is utilized to successfully demonstrate a simple spectroscopic measurement of N₂O gas.
