Dec 18, 2017 · We propose a modularized architecture of a large-scale optical phased array (OPA) on a silicon on insulator (SOI) platform, using electro-optical (EO) pixels.

Our MEMS OPA is capable of randomly accessing multiple optical beams within the FOV of 4.4°×4.6° at 1550nm wavelength, and potentially with optical efficiency as high as 90%.

Using a silicon photonic OPA chip with 128 carrier-depletion-based phase shifters, we experimentally confirm this property by successfully retrieving an image under a maximum …

Nov 28, 2022 · An optical phased array (OPA) is a compact high-speed wavefront modulation device that is promising for next-generation optical sensing systems. In particular, speckle …
