Abstract:
The optoelectronic oscillation using the second harmonic of a period-one (P1) oscillation as the oscillation seed is proposed and experimentally demonstrated. The P1 oscillation was generated by a distributed feedback (DFB) laser subject to optical feedback. By using a bandpass electrical amplifier to provide sufficient gain for the second harmonic frequency of the P1 oscillation, frequency-doubled microwave signal was generated with the single sideband phase noise below -114.2 dBc/Hz at a 10-kHz frequency offset from the carrier.
