Abstract
An optical system has a beam-steering device, a light source, and a controller that controls the light source to actively control wavelength of the incoming light to control the output angle of the outgoing light output from the BS device. The BS device may have incoupler, waveguide, and/or outcoupler electrodes, and the system may have corresponding controllable voltage supplies actively controlled by the controller to selectively modify electric fields applied to the BS device to control corresponding operating characteristics of the BS device (e.g., in-plane and/or out-of-plane output angles of the outgoing light and/or device incoupling angle). An alternative optical system has a BS device, a detector array that generates detector signals corresponding to outgoing light received from the BS device, and a controller that processes the detector signals to determine one or more wavelengths of the outgoing light.
