Application: Photonic integrated circuit temporal and frequency dispersion squint correction for optical phased array (Patent ID: US20230417985A1)

The patent filed by RTX Corp describes an apparatus that includes a photonic integrated circuit with an optical phased array and multiple arms. The optical phased array consists of unit cells with antenna elements for transmitting or receiving optical signals, while the arms are controllable to provide temporal squint correction and frequency dispersion squint correction. The circuit may also include electro-optic modulators for controllable delays and dispersive compensation elements for adjusting phase-frequency relationships to correct frequency dispersion squint.

The claims associated with the patent detail the specific components and functionalities of the apparatus, such as semiconductor optical amplifiers for signal amplification, electro-optic modulators for delay control, and dispersive compensation elements for adjusting phase-frequency relationships. The method outlined in the claims involves transmitting or receiving optical signals using the photonic integrated circuit and controlling the arms to provide squint correction. Additionally, the method includes utilizing a cascaded arrangement of modulators for phase and dispersion control, as well as ensuring that the arms of the circuit are phase-locked with each other. Overall, the patent focuses on the development of an apparatus and method for precise control and correction of optical signals within a photonic integrated circuit.
