Abstract: PURPOSE: A tera-hertz continuous wave generator is provided to establish a wired/wireless ultra-wideband convergence network with super high speed without discontinuity and delay through seamless connection with an optical network. CONSTITUTION: An optical intensity modulator(20) modulates an inputted optical signal into a double sideband optical signal by using frequencies and power from a local oscillator(30). The local oscillator generates a modulated signal for modulating the optical signal inputted in the optical intensity modulator into the double sideband optical signal. An optical fiber amplifier(40) amplifies an output signal from the optical intensity modulator. An optical circulator(50) transfers the optical signal inputted in the optical fiber amplifier to a notch filter(60). The notch filter filters the optical signal inputted from the optical circulator. An opto-electric converter(70) is used as a photo mixer photo-mixing the double sideband signal outputted from the notch filter.
