Abstract: An apparatus includes a substrate and an optically powered surface. The substrate is transmissive of electromagnetic energy, and includes a plurality of reflective portions oriented and positioned to control a propagation direction of electromagnetic energy along an optical path of the substrate. The substrate further includes an input surface aligned with the optical path so as to allow electromagnetic energy to enter the substrate through the input surface. The optically powered surface is positioned relative to the substrate so as to redirect a field of view of the substrate. The field of view of the substrate is bounded by a first angular width, a field of view of the optically powered surface is bounded by a second angular width, and the second angular width is different than the first angular width.

Abstract: An electrical circuit assembly can include a semiconductor integrated circuit, such as fabricated including CMOS devices. A first lateral-mode resonator can be fabricated upon a surface of the semiconductor integrated circuit, such as including a deposited acoustic energy storage layer including a semiconductor material, a deposited piezoelectric layer acoustically coupled to the deposited acoustic energy storage layer, and a first conductive region electrically coupled to the deposited piezoelectric layer and electrically coupled to the semiconductor integrated circuit. The semiconductor integrated circuit can include one or more transistor structures, such as fabricated prior to fabrication of the lateral-mode resonator. Fabrication of the lateral-mode resonator can include low-temperature processing specified to avoid disrupting operational characteristics of the transistor structures.
