The study reports linear optical isolation of 10 dB, and experimental measurement of one-way, no-loss digital data transmission on an optical signal carrier. Our integrated, linear, magnetic-free, electrically driven optical isolatorĬould become key building blocks for integrated lasers, chip-scale LiDARĮngines, as well as optical interfaces for superconducting circuits. Though magnet-free optical isolators have been introduced previously, the collaborative work produced the first that is driven electrically and operated in the linear optical regime. The isolation remains constant over nearly 30ĭB dynamic range of optical input power, showing excellent optical linearity. Isolation is achieved under 100 mW RF power applied to each actuator, with Rotating acoustic wave that allows indirect interband transition in only oneĭirection among a pair of strongly coupled optical modes.
