Abstract
Disclosed herein are various embodiments of an optical cross-connect switch in which optical beamforming is used to generate desired (e.g., technically beneficial) beam profiles at the beam-steering element of the switch. An example beam profile that can be generated in this manner is a substantially rectangular beam profile generated from an input optical beam having a substantially Gaussian beam profile. The use of rectangular beam profiles may be beneficial because such beam profiles can be used to increase the optical fill factor of the beam-steering element of the switch, thereby enabling the switch to have a higher number of optical ports and/or a lower cost per optical port than comparable conventional optical cross-connect switches. In an example embodiment, the disclosed optical cross-connect switch can be used to implement a wavelength-selective optical router.
