<P>PROBLEM TO BE SOLVED: To provide an optical oscillator which can generate a desired pulse light frequency easily with a simple configuration, and to provide a recording device. <P>SOLUTION: The optical oscillator and the recording device are configured to include a supersaturation absorber 2 having a double quantum well separation confinement heterostructure and applying a negative bias voltage, a self-oscillation semiconductor laser 1 including a gain section 3 for injecting a gain current, and a control unit 38 which controls the gain current being injected into the gain section 3 of the self-oscillation semiconductor laser 1 on the basis of the phase difference between the oscillation light emitted therefrom and a master clock signal, or a control unit 45 which controls the negative bias voltage being applied to the supersaturation absorber 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
