OPTICAL DETECTOR, OPTICAL RECEIVER, AND METHOD FOR QUANTUM COMMUNICATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240333399 titled 'OPTICAL DETECTOR, OPTICAL RECEIVER, AND METHOD FOR QUANTUM COMMUNICATION
Simplified Explanation: The patent application describes an optical detector for quantum communication that utilizes a photonic lantern to split a spatial multi-mode input signal into orthogonal single-mode output signals, which are then combined to form a single-mode combined output signal for detection by a photodetector assembly.
- The optical detector includes a photonic lantern with a multi-mode input port and single-mode output ports connected by light channels.
- The photonic lantern splits the input signal into mutually orthogonal single-mode output signals.
- A coherent beam combiner combines the single-mode output signals into a single-mode combined output signal.
- A photodetector assembly with single photon counters detects the combined output signal to provide a detection signal.
