All-in-one 100-Gbit/s DP-QPSK coherent receiver using novel PLC-based integration structure with low-loss and wide-tolerance multi-channel optical coupling

We have successfully demonstrated an all-in-one coherent receiver for 112-Gbit/s DP-QPSK signal detection by developing a new silica-based PLC hybrid integration technology with multi-channel micro collimator optics and hermetically sealed O/E converters.
