Driven by the demands for speed and field of view in the holographic photostimulation community, we designed, built, and tested a liquid crystal on silicon (LCoS) spatial light modulator (SLM) with a 1536x1536 square pixel array and high-voltage LC d

INTRODUCTION Perceptual experiences in mammals may arise from patterns of neural circuit activity in cerebral cortex. For example, primary visual cortex (V1) is causally capable of initiating visual perception; in human neurosurgery patients, V1 elec

Polarization gratings (PGs) enable a novel architecture for dynamic non-mechanical steering of light over large angles and with large clear apertures. This beam steering approach has many applications in active sensing and optical communications. In

We report on the construction and testing of a 128 by 128 Electroclinic effect Spatial Light Modulator. The silicon backplane has pixels on a square array with a pitch of 40μm. It was implemented in a lightly-doped-drain high-voltage CMOS process wh

Ferroelectric liquid crystal spatial light modulators can be used to display high quality binary phase holograms, and incorporated into programmable free space interconnects. These are potentially highly efficient, and have advantages over convention
