Abstract:
A novel scheme for the generation and stabilization of the millimeter-wave (mmW) signal employing a frequency-demultiplication optoelectronic oscillator (FD-OEO) has been theoretically analyzed and experimentally demonstrated. The FD-OEO can keep sustaining without optical first-order sidebands, which would help to simplify the photonic-assisted frequency multiplication process and provide a wide frequency compensation range for the mmW system simultaneously. The stability of the generated 40-GHz mmW signal reaches 1.38 × 10-12 at the average time of 100s. Besides, the measured single-sideband phase noise of the generated mmW signal exhibits as low as -103 dBc/Hz at 10-kHz offset frequency, maintaining a spurious level of -97 dBc.
