US 2026/0110837 A1 · PHOTONIC DEVICES AND STRUCTURES FOR OPTICAL EPOXY/OIL OVERFLOW CONTROL

Abstract

A photonic system includes a photonic device, a first set of bulk optics components, a second set of bulk optics components, and optical fill material. The photonic device includes a semiconductor substrate, a dielectric layer, a first set of optical ports, a second set of optical ports, and one or more overflow structure between the first and second set of optical ports. The semiconductor substrate includes a top side, a bottom side, and a lateral side. The dielectric layer includes a top side, a bottom side on the top side of the semiconductor substrate, and a lateral side. The optical fill material fills a first interface between the first set of bulk optics components and the first set of optical ports. The one or more overflow structures provide one or more voids to receive optical fill material that overflows from the first interface.
