  We demonstrate a free running 10GHz microresonator-based RF photonic
hyper-parametric oscillator characterized with phase noise better than
-60dBc/Hz at 10Hz, -90dBc/Hz at 100Hz, and -150dBc/Hz at 10MHz. The device
consumes less than 25mW of optical power. A correlation between the frequency
of the continuous wave laser pumping the nonlinear resonator and the generated
RF frequency is confirmed. The performance of the device is compared with the
performance of a standard optical fiber based coupled opto-electronic
oscillator of OEwaves.
