The optical oscillator comprises 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 polarizing 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 polarizing effect by means of the dispersion-compensating optical fiber, and a polarizing 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. Therefore, two laser modes are simultaneously oscillated so that ultra-high frequencies (60, 120 and 160 GHz) are modulated due to Magnolia phenomenon between the two laser modes.
