Abstract
An optical device may include a monolithic beam steering engine. The device may include a twin M×N wavelength selective switch (WSS) including a first M×N WSS and a second M×N WSS. The first M×N WSS may include a first panel section of the monolithic beam steering engine to perform first beam steering of first beams, wherein the first beam steering is add/drop port beam steering; and a second panel section of the monolithic beam steering engine to perform second beam steering of second beams, wherein the second beam steering is common port beam steering. The first M×N WSS may include a first optical element aligned to the monolithic beam steering engine to direct one of the first beams or the second beams relative to the other of the first beams or the second beams, such that the first beams are directed in a different direction from the second beams.
