Abstract
Optoelectronic oscillators (OEOs) with their demonstrated low phase noise are popular due to the increasing demand of very clean local oscillator and clock signal sources. A forced technique of self-injection locked and phase-locked loop (SILPLL) reduces phase noise and suppresses side mode observed in long fiber delay of the standard OEO. A frequency synthesizer working at X-band is developed using an electrically coarse-tuned YIG filter cascaded with an optical wavelength fine-tuned dispersive optical transversal filter by tuning the oscillation frequency of the synthesized OEO frequency, as a replacement for fixed-frequency narrowband filter using high-Q aluminum cavities. A close-to-carrier phase noise of -115 dBc/Hz at 1 kHz is reported by the V π/2 operation of a Mach-Zehnder modulator (MZM) over 8-12 GHz with a frequency tuning step as small as 2.6 kHz. Phase noise introduced by a photodetector is also explored at a very close-to-carrier frequency. It shows 10-dB phase noise degradation at PD reverse bias voltage of 3 V compared with 6 V at close to the Vπ operation of an MZM. A 19-in rack mount frequency synthesizer system is also realized at X-band with a demonstrated long-term (up to 60 min) frequency drift stability of 3 kHz over whole X-band working frequencies.
