Large-Scale Visible and Infrared Optical Phased Arrays in Silicon Nitride

Not Accessible

Your library or personal account may give you access

Abstract

Large-scale optical phased arrays at 635nm and 1550nm wavelengths are demonstrated with aperture sizes up to 4 × 4mm2. A diffraction limited spot with a record 0.021°×0.021° divergence and output powers as high as 400mW are shown.
