COMPLEX-WAVEFRONT PHOTONIC TRANSCEIVER PROCESSOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240039638 titled 'COMPLEX-WAVEFRONT PHOTONIC TRANSCEIVER PROCESSOR

Simplified Explanation

The abstract describes a complex-wavefront photonic transceiver that includes a coherent source and a complex transmitter waveform generator. The transmitter waveform generator is programmable to modulate a first portion of the coherent electromagnetic radiation received from the coherent source to form a complex waveform. This complex waveform includes pre-distortion to compensate for or adaptive beamforming to determine distortion caused by the transceiver or during transmission to a receiver aperture. The receiver aperture outputs receiver signals in response to the complex waveform, and a transmitter aperture transmits the complex waveform received from the complex transmitter waveform generator. The transceiver also includes a receiver processor that is programmable to determine the phase and amplitude of the complex waveform received on the receiver aperture from a combination of the received signals with a second portion of the electromagnetic radiation.
