摘要：
We report generation of terahertz (THz) radiation in a planar 61-mu m-thick GaAs waveguide with a TM0 propagation mode, achieved by phase-matched difference frequency mixing. The THz output was centered near 2 THz and had 1 mu 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 mu m with the average powers of 250 and 750 mW, correspondingly.
