Metro-access networks are a type of optical network connecting metro hubs with various subnetworks, covering from rural to dense urban regions. In the long term, the metro-access network is expected to address hundreds of Tb/s aggregated traffic, which makes spectral efficient multiplexing techniques a must-have. Combining wavelength division multiplexing (WDM) and digital subcarrier multiplexing (DSCM) techniques is a possible successful industrial approach to cope with this challenge.

Abstract We present an ultra-wide band photonic integrated ${{4}} \times {{4}}$ polymer cross-bar switch matrix based on total internal reflection and the thermo-optic effect. The photonic integrated polymer switch owns low insertion loss, low power consumption, wavelength, and polarization-independent operation for all switching paths.
