WDM COMB SOURCE BASED OPTICAL LINK WITH IMPROVED OPTICAL AMPLIFICATION

摘要

A receiver (RX) for an optical link configured to decode at least one data stream (c-c) from an optical signal (IN) transmitted by a transmitter (TX) of the optical link, wherein the optical signal (IN) comprises a plurality of optical carriers with different frequencies (f) and a plurality of the optical carriers have been modulated according to a data stream (c-c) by respective modulators (FSM, RRM, MZM), wherein the receiver (RX) comprises a polarization splitting element (PSC) with one input port and two output ports, at least one resonant add-drop multiplexer (ADM) tuned to at least one optical carrier modulated according to a data stream (c-c), and at least one detector (PD) to convert a light intensity into an electrical signal, wherein light from the two output ports of the polarization splitting element (PSC) is coupled into the resonant add-drop multiplexer (ADM) in opposite directions, and that light is coupled from the resonant add-drop-multiplexer (ADM) to the at least one detector (PD) in two opposite directions.
