Abstract
A scalable independent unit cell device architecture may include a phase-shifting element and a phase shift driver both integrated within the unit cell device. The phase shift driver may be coupled to the phase-shifting element and the phase shift driver may independently control the phase-shifting element to produce an optical beam having a desired phase. The unit cell device may further include an optical antenna that outputs the beam having the desired phase. The unit cell device may be formed as an opto-electronic hybrid optimized to leverage direct bond hybridization (DBH) to attach an electronic integrated circuit wafer to a side of a photonic integrated circuit wafer. The resulting unit cell device (i.e., 24 microns) may tightly integrate individual element-level phase control, which may be implemented within large-scale two-dimensional photonic arrays with hemispherical beam steering.
