  • Publication number: 20240333399
    Abstract: An optical detector for quantum communication, comprising a photonic lantern comprising a multi-mode input port to receive a spatial multi-mode input signal, and a plurality of single-mode output ports connected to the multi-mode input port by respective light channels. The photonic lantern splits the input signal by guiding the input signal in the individual light channels into a plurality of mutually orthogonal spatial single-mode output signals and outputs the plurality of single-mode output signals through the single-mode output ports. A coherent beam combiner combines the single-mode output signals to form a single-mode combined output signal. A photodetector assembly comprising one or more single photon counters detects the combined output signal to provide a detection signal.
