Abstract
A photonic integrated circuit (PIC) structure includes a substrate, and a cavity defined in the substrate, the cavity including a shoulder at a side of the cavity. A plurality of z-stop supports for an optical device are also included. Each z-stop support of the plurality of z-stop supports is on a support portion of the shoulder. A wire extends over the side of the cavity and between at least two z-stop supports of the plurality of z-stop supports. An optical device is positioned on the plurality of z-stop supports in the cavity and electrically coupled to the wire. Electrical connections between z-stop supports allows larger sized electrical connections to the optical device to mitigate electromigration issues, and increased options for electrical connections.
