Abstract
A triple band frequency generator based on the optoelectronic oscillator (OEO) with low phase noise has been proposed and experimentally demonstrated. In this novel scheme, the phase-coherent triple band frequency in C, Ku and K bands can be achieved simultaneously by biasing the first modulator in the oscillation loop at the minimum transmission point (MITP) and the second modulator near the MITP with a small deviation. In the proof-of-concept experiment, the triple band frequency signals at 5.36, 16.08 and 21.44 GHz are generated with the phase noise of -123.32, -113.68 and -111.19 dBc/Hz at 10 kHz offset frequency, respectively. The proposed scheme provides a novel strategy for phase-coherent multi-band frequency and low phase noise signals generation, which can be potentially used in the multi-function and multi-band frequency electrical systems.
