US 12,754,376 B2 · Electro-optical circuits with modular switchable photonic interface

Abstract

An integrated circuit (IC) module includes a photonic IC, an electrical IC, and a switchable waveguide device that, using a signal from the electrical IC, controls optical signals to or from the photonic IC. The switchable waveguide device may be formed by coupling metallization structures on both sides of, and either level with or below, a nonlinear optical material. The metallization structures may be in the photonic or electrical IC. The nonlinear optical material may be above the electrical IC in the photonic IC or on a glass substrate. The photonic and electrical ICs may be hybrid bonded or soldered together. The IC module may be coupled to a system substrate.
