Millimeter-Wave to Telecom Electro-Optic Frequency Transduction on Thin-Film Lithium Niobate

ORAL

Abstract

Electro-optic frequency transduction of microwave-to-optical photons is one promising avenue for linking cryogenic quantum nodes. In particular, millimeter wave (mmW) superconducting systems at high frequencies (~105 GHz) enable high microwave-optical photon couplings and greater pump-power compared to lower-frequency (~5 GHz) transduction. We demonstrate this technology via triply-resonant mmW (~105 GHz) to telecom (~193 THz) frequency conversion. Our device consists of a NbTiN mmW resonator atop thin-film lithium niobate, with a sapphire substrate. In our preliminary results, we study the coupling rate between optical and mmW photons and determine conversion efficiency. As next steps, we aim to study converted sideband asymmetry for mode thermometry and other optomechanical phenomena in the mmW regime. Our work demonstrates a first step toward coherent microwave-to-optical transduction mediated by mm-waves.
