GOLDEN, Colo., April 29, 2015 — A nonmechanical beam-steering device from Vescent Photonics Inc. operates at the crossroads of waveguide and liquid crystal (LC) technologies. The SEEOR (Scannable Electro-Evanescent Optical Refractor) can continuously steer a near-infrared laser beam over a 30° × 5° field of view with a full frame rate <50 ms. The beam is refracted by prismatic structures in an LC-based cladding to the waveguide. The electro-optic coefficient of the LC (up to 100,000 times that of LiNbO3) allows voltage tuning of the index of the prisms, and hence the refraction angle of the...See full product
