  • Optical phase array, methods of forming and operating the same
    Patent number: 11320717
    Abstract: Various embodiments may provide an optical phase array. The optical phase array may include a laser source configured to emit a laser. The optical phase array may further include an integrated photonic network with n stages of optical splitters, the optical splitters being 1 ? 2 optical splitters, each optical splitter of the integrated photonic network having an input, a first output, and a second output. The integrated photonic network may be configured to separate the laser into N outputs. Each output of the N outputs may differ from a neighbouring output of the N outputs by a constant phase difference (??). N may be equal to 2 to the power of n.
