Abstract
Low-frequency fluctuations in semiconductor lasers with optical feedback are investigated when high-frequency modulation is applied to an injection current. Synchronization of the laser output power with the modulation within ±3 MHz centered at the frequency corresponding to the external cavity mode was observed. However, for modulation of the detuned frequency from the external cavity mode, low-frequency fluctuations were induced in the laser output power, and these fluctuations were observed within a range of modulation of approximately ±100 MHz at the center frequency of the external cavity mode.
