  • System and method for breaking time-reversal symmetry with acoustic pumping of nanophotonic circuits
    Patent number: 10690856
    Abstract: Systems and methods provide a nonreciprocal nanophotonic modulator. In some examples, the modulator utilizes acoustic pumping, instead of optical pumping with lasers, and is capable of achieving GHz bandwidth.
    Type: Grant
