Nanophotonic Modulator using Electromagnetically Induced Transparency

"The proposed high bandwidth electro-optic modulator uses an optical waveguide microcavity to enhance the interaction of optical fields with a material that exhibits coherent quantum attributes. The nonlinear characteristic of the light - matter coupling inconcert with the resonance requirements of the microcavity provide a sensitive modulation mechanism. In the device the combination of nanophotonic and quantum interference effects can respond to low signal levels at high bandwidth. Electro-optic modulatorsface stringent emerging specifications to operate at higher bandwidth in response to lower drive signals as electronic processors and data communication link characteristics improve. Applications exist in chip-to-chip data transfer and in multiplexedcommunication network routing. A specific need has been identified to transfer RSFQ-level signals from cryogenic electronics to an optical carrier."
