Photonics-based high purity microwave oscillators at 10 GHz

We report on recent works on photonics based architectures for the generation of high purity RF signals. Different configurations of 10 GHz fixed frequency optoelectronic oscillators are studied (dual-loop, all-photonic gain, and coupled). All these configurations provide phase noise below -90 dBc/Hz at 100 Hz frequency offset, and below -140 dBc/Hz above 10 kHz frequency offset. Every configuration exhibits state-of-the-art phase noise performances. Integration perspectives are also given, with preliminary acceleration sensibility measurements.
