description The integrated network element offers an efficient fiber-chip coupling of multiple outputs of a polarization sensitive photonic integrated circuit (PIC) using a programmable mirror co-packaged with the PIC. Efficient fiber-chip coupling requires precise and active alignment of all free-space components. These constraints can be reduced by using a programmable mirror in the form of a liquid crystal on silicon (LCoS) device. The LCoS can be programmed with patterns that offer highly accurate beam-steering and focusing functionality. Imaging optics may be used at the PIC facet to provide some degree of collimation in the free-space optical path to efficiently illuminate the LCoS. By reprogramming the LCoS switching between two outputs/inputs can be obtained at high speed.
