With their very large bandwidth and fast switching speed, optical cross-connects will play an important role in the future broadband transport and access networks. There are two technologies, wavelength-division and space-division multiplexing, which have been extensively studied for optical cross-connects [1]–[5]. Each of them has its strength and limitation. WDM can provide a simple structure to implement a broadband cross-connect, but there are some technological challenges, such as the tunability of components, their tuning speed, and wavelength stability. Semiconductor optical amplifiers (SOA) based space switches are also very competitive as optical cross-connects [5]. SOA’s can compensate for the system loss and provide a high on/off ratio with a broad optical bandwidth. However, the size of the cross-connects becomes limited due to the difficulties in component integration.
