Steering a laser usually means moving a mirror or gimbal — mechanical, slow, and a wear point. US11962346B2, granted to Raytheon Company on April 16, 2024, does it with no moving parts, claiming a "photonic integrated circuit (PIC)-based optical phased array with integrated gyroscopic sensor."

The CPC is optical-comms and optics: H04B 10/1129 and 10/1127 (free-space optical transmission, beam acquisition/tracking) and G02B 6/359 (optical waveguide switching). The waveguide code is the photonic-chip giveaway — the beam steering happens in integrated optics, not bulk hardware.

“An apparatus includes a photonic integrated circuit having an optical phased array, where the optical phased array includes multiple unit cells.”— U.S. Patent No. 11,962,346 source

The mechanism mirrors RF phased arrays, in light. Just as an RF array steers a radio beam by controlling the phase across many elements, an optical phased array steers a laser by controlling the phase across many waveguide emitters on a photonic chip. Integrating the array onto a PIC makes it compact, rugged, and fast. The added gyroscopic sensor provides inertial reference to stabilize and point the beam — critical when the platform is moving.

For laser communication and sensing, this is enabling miniaturization: a beam-steering subsystem that can be manufactured like a chip rather than assembled like an instrument. The defense-tech relevance is obvious — directed energy, precision sensing, and secure optical links all want exactly this kind of compact, no-moving-parts pointing.

A security-aware note this desk always makes: Raytheon's public patent record shows the commercializable and dual-use edge of its work; the most sensitive directed-energy and sensing applications live in classified programs the public record does not reach. This grant claims a specific PIC-based optical-phased-array-plus-gyro implementation, not optical phased arrays in general. It is a clear window into where photonics is heading — and a reminder that what is patented is only the part the company is willing to show.
