Electronic Devices with High Frequency Polarization Optimization - A simplified explanation of the abstract
This abstract first appeared for US patent application 17827329 titled 'Electronic Devices with High Frequency Polarization Optimization
Simplified Explanation
The patent application describes a system for wireless communication using optical signals with different polarizations. It includes a first device that generates optical signals, photodiodes that convert the optical signals into wireless signals at different polarizations and frequencies above 100 GHz, and a second device that receives and converts the wireless signals back into optical signals. The second device uses a Stokes vector receiver to generate Stokes vectors based on the optical signals, and control circuitry to generate a rotation matrix that characterizes polarization rotation between the two devices. The rotation matrix is then used to mitigate polarization rotation and other transmission impairments in subsequently received wireless signals.

Original Abstract Submitted
A first device may generate optical signals of different polarizations. Photodiodes may use the optical signals to transmit wireless signals at different polarizations and at a frequency greater than 100 GHz using the optical signals. A second device may receive the wireless signals and may convert the wireless signals into optical signals. A Stokes vector receiver on the second device may generate Stokes vectors based on the optical signals. Control circuitry on the second device may use the Stokes vectors generated for a series of training data in the wireless signals to generate a rotation matrix that characterizes polarization rotation between the first and second devices. The control circuitry may multiply wireless data in subsequently received wireless signals by the rotation matrix to mitigate the polarization rotation and other transmission impairments while using minimal resources.
