Application: Photonic integrated circuit (PIC)-based optical phased array with integrated gyroscopic sensor (Patent ID: US20240056184A1)

The patent filed by Raytheon Technologies Corp. describes an apparatus that includes a photonic integrated circuit with an optical phased array consisting of multiple unit cells. Each unit cell has an antenna element for transmitting or receiving optical signals and a phase modulator to modify the phases of these signals. Additionally, the apparatus incorporates a gyroscopic sensor to detect movement of the photonic integrated circuit, with at least a portion of the sensor integrated within the circuit. The system also features a phase controller to adjust the optical phased array based on the movement sensed by the gyroscopic sensor and samples of optical signals received from an external node.

Furthermore, the patent outlines various claims related to the apparatus, including the positioning of the gyroscopic sensor within the layers of the photonic integrated circuit, the use of a tracking system with an imaging sensor to identify movement, and the adjustment of the optical phased array to maintain an optical link with the external node during circuit movements. The method described involves transmitting and receiving optical signals using the photonic integrated circuit, sensing movement with the gyroscopic sensor, and adjusting the optical phased array based on the detected movement and received signal samples. Overall, the patent focuses on the integration of a gyroscopic sensor within a photonic integrated circuit to enable precise adjustments and maintain optical connectivity in response to circuit movements.
