Abstract :
Optoelectronic generation of continuous THz radiation with a compact, high power DFB laser which operates simultaneously on two longitudinal modes corresponding to the fundamental and first-order lateral modes is demonstrated. The spectral mode spacing is 0.45 nm. THz emission is obtained by mixing the two-line laser emission in an LT-GaAs 0.81Sb0.19 photomixer
