- W4317941807 abstract "Photonic integrated circuit based optical phased arrays (PIC-OPA) are emerging as promising programmable processors and spatial light modulators, combining the best of planar and free-space optics. Their implementation in silicon photonic platforms has been especially fruitful. Despite much progress in this field, demonstrating steerable two-dimensional (2D) OPAs scalable to a large number of array elements and operating with a single wavelength has proven a challenge. In addition, the phase shifters used in the array for programming the far field beam are either power hungry or have a large footprint, preventing implementation of large scale 2D arrays. Here, we demonstrate a two-dimensional silicon photonic phased array with high-speed (~330 KHz) and ultralow power microresonator phase-shifters with a compact radius (~3 {mu}m) and 2{pi} phase shift ability. Each phase-shifter consumes an average ~250 {mu}W static power for resonance alignment and ~50 {mu}W power for far field beamforming. Such PIC-OPA devices can enable a new generation of compact and scalable low power processors and sensors." @default.
