A Cylindrical Lens-based Integrated 2D Beam-steering Device Using Staircase Grating Emitters

Not Accessible

Your library or personal account may give you access

Abstract

A 15°*12° integrated two-dimensional beam-steering device based on an on-chip silicon-nitride switch/emitter structure and off-chip cylindrical lens is demonstrated. The staircase grating emitters allow a directional emission greater than 90%.
