High-power two-wavelength phase-locked laser beams (optical frequencies ν₁, ν₂) have been generated by optical injection synchronization of a DFB laser pair with an optical frequency difference set to 101 GHz into an electro-optic modulator-based optical comb (EOM comb), and an unmodulated THz wave (frequency 1 GHz) has been generated by using these as optical carriers in an optical waveguide propagated EOP modulator The RF beat signals (frequency 1 GHz) of the ν₁ modulation sideband and ν₂ carriers were detected by irradiating the EOP modulator (frequency 100 GHz) with these as optical carriers. Prior to the detection of the modulated THz wave, a theoretical study on all-optical THz detection was carried out.
