Abstract

We report generation of terahertz (THz) radiation in a planar 61 - μ m -thick GaAs waveguide with a TM 0 propagation mode, achieved by phase-matched difference frequency mixing. The THz output was centered near 2 THz and had 1 μ W average power. As a pump source we utilized both the signal and the idler outputs of a near-degenerate type II synchronously pumped optical parametric oscillator operating near 2 μ m with the average powers of 250 and 750 mW , correspondingly.
