Frequency Multiplexed Optical Entangled Source based on the Pockels Effect

In the recent years important experimental advances in resonant electro-optic modulators as high efficient sources for coherent frequency combs and as devices for quantum information transfer have been realized, where strong optical and microwave mode coupling were achieved. These features suggest electro-optic based devices as candidates for entangled optical frequency comb sources. In the present I study the generation of entangled optical frequency combs in mm-sized resonant electro-optic modulators. These devices profit from the experimentally proven advantages such as nearly constant optical free spectral ranges over several gigahertz, high optical and microwave quality factors. The generation of frequency multiplexed quantum channels with spectral bandwidth in the range of a MHz for conservative parameter values paves the way towards novel uses in long distant hybrid quantum networks, quantum key distribution, enhanced optical metrology and quantum computing.
