Abstract:
1. An optical signal output apparatus that outputs an optical pulse pattern signal including jitter, the optical signal generating apparatus comprising: a light source section that outputs an optical signal having an optical frequency corresponding to a frequency control signal; an optical modulation section that modulates the optical signal output by the light source section, according to a designated pulse pattern; an optical jitter generating section that delays an optical signal passed by the optical modulation section according to the optical frequency, to apply jitter to the optical signal; and an optical intensity adjusting section that compensates for optical intensity change of the optical signal from the light source section and outputs an optical signal in which intensity change caused by change of the optical frequency is restricted, wherein the optical intensity adjusting section adjusts an amplification factor of the input light from the light source section, based on the frequency control signal, to restrict optical intensity change of the optical signal output by the light source section according to the frequency control signal, and outputs the resulting optical signal.
