A new generation of high-speed electro-optical transceivers and flexible bandwidth wavelength selective switches for coherent DCI The QAMeleon project approach Zervos, C.; Spyropoulou, M.; Kanakis, I.;  ...  QAMeleon ROADM concept is based on the hybrid integration of InP photonic integrated circuits (PICs) with Liquid Crystal on Silicon (LCoS) technology using an Electro-Optic Polymer Board (EOPCB) replacing  ...  For example, a ROADM is modelled as a set of interconnected WSSs and TPAs, where each of them is controllable and/or configurable as single functional entities.  ...
