Abstract
Properties of the optoelectronic microwave oscillator (OEO) based on an optical whispering gallery mode lithium niobate disc cavity are studied theoretically. We show that the threshold of the oscillation of this device may be as low as 1 mW, and its frequency stability (Allan deviation) may be as small as 10−15/t 1/2 for reasonable experimental conditions. The properties of resonant and non-resonant OEOs are compared. Preliminary experimental results on the whispering gallery mode OEO are reported.
