A beam steering optical phased array (OPA) may include an optical signal distributor including a plurality of output terminals configured to divide and output input optical signals and phase shifters arranged at the plurality of output terminals and configured to receive the divided optical signals ...
As phased arrays become ubiquitous in both military and civilian applications, beamsteering and beam stabilization are two hot topic areas. These concepts allow end system designers to improve system performance by pinpointing and focusing radiation beams from the array. This allows the system to more...
