摘要：

A frequency encoded all optical N bitcomparator is proposed. The implementation is ultrafast one and the frequency encoding makes it intensity loss dependent problem free. The use of polarization insensitive four wave mixing makes the design polarization independent and the hardware simple. The frequency conversion by the RSOA makes the design faster compared to other SOA based design. The required gates. i.e. X-OR and AND gates for the implementation of the comparator in frequency encoded format are also discussed. (C) 2011 Elsevier GmbH. All rights reserved.
