5 February 2013 Filter-bank based digital sub-banding ASIC architecture for coherent optical receivers
Author Affiliations +
We introduce a highly efficient high performance architecture for the digital signal processing of high speed coherent optical receivers. Our ASIC signal processing architecture ports for the first time to optical reception efficient filter bank signal processing structures. The resulting optical receiver ASICs are applicable to long-haul and metro photonic communication and provide substantial energy efficiency saving 30%-50% in power consumption. We aim to develop an ultra-high-speed optical receiver ASIC for transporting 160 Gb/s in a 25 GHz optical band - seven such channels will together carry 1Tb/s (plus overhead) in our 'TeraSanta' project of TeraBitPerSecond efficient transponders.
