Patent ID: 11668876

Abstract:
An optical beam steering device is provided that includes an input optical fiber carrying multiple input optical signals, where each input optical signal includes a unique wavelength, an arrayed waveguide grating router (AWGR) having multiple output fibers, where the input optical fiber is connected to the AWGR, distal ends of the output fibers are arranged in a two-dimensional fiber array, the input optical signals are routed by the AWGR according to each unique wavelength to a unique AWGR output fiber, and a lens, where the distal ends of the output fibers are disposed proximal to a focal plane of the lens, where for each unique position of each output fiber distal end with respect to a the lens, each input optical signal is steered at a unique angle as an output beam emitted from the lens, where changing the wavelength of the input optical signal changes the output signal angles.
