Abstract
A compact and easily manufacturable waveguide optical frequency router ( ) is provided. The router ( ) has a transmit core region ( ) and a plurality of receive core regions ( ) formed within a slab region ( ). The router ( ) further includes an array of distributed Bragg deflectors (DBDs) ( ) formed within the core regions ( ) for coupling optical energy ( ) between the transmit core region ( ) and the receive core regions ( ) via the slab region ( ). The array of DBDs ( ) distributes the optical energy ( ) between the receive core regions ( ) based on optical wavelength and propagation angle.
