Abstract:
An optical oscillator with milimeterwave frequency, comprising:a non-linear circuit including a wavelength coupler for receiving a pump light, an optical amplification optical fiber for amplifying the light from the wavelength coupler, a dispersion-compensating optical fiber for obtaining a non-linear polarization effect of the light transmitted via the optical amplification optical fiber, a line polarizer for varying the wavelength of the light having a non-linear polarization effect by means of the dispersion-compensating optical fiber, and a polarization controller for controlling the modulating frequency of the light transmitted via the line polarizer; an output circuit having an optical direction indicator for precluding the path of the light, a 10% optical fiber coupler for output light, and a dispersion-compensating optical fiber for determining the wavelength region; and an optical coupler for connecting the non-linear circuit and the output circuit.
