This work demonstrates Cherenkov-type generation and detection of terahertz (THz) waves in GaAs at 1.55-μm excitation and optical sampling probe, respectively. Results show that GaAs with metal-coat (M-G-M) has better performance than a bare GaAs (BG), both as an emitter and a detector because of im...
