Abstract
An optical beam scanning semiconductor device includes 1×N electrically controlled, integrated optical switch matrix and specifically designed integrated optical grating output couplers at each of N output waveguides of 1×N switch. By selecting one of the N outputs of the 1×N switch as the output of the input optical signal, an optical output beam scans in free space. Variation in the grating output coupler design enables a smart scanning device with multiple controllable beam characteristics.
