Introduction Integrated photonic technologies are rapidly becoming an important and fundamental milestone for wideband optical telecommunications. Future optical networks have several critical requirements including low energy consumption high efficiency greater bandwidth and flexibility which must be addressed in a compact form factor Eggleton et al. 2008 Alduino Paniccia 2007 Lifante 2003 . In particular it has become well accepted that devices must possess a CMOS compatible fabrication procedure in order to exploit the large existing silicon technology in electronics Izhaky et al. 2006 Tsybeskov et al. 2009 . This would primarily serve to reduce costs by developing hybrid electro-optic technologies on-chip for ultrafast signal processing. There is still however a growing demand to implement all-optical technologies on these chips for frequency conversion Turner et al. 2008 Venugopal Rao et al. 2004 all-optical regeneration Salem et al. 2008 Ta eed et al. 2005 multiplexing and demultiplexing Lee et al. 2008 Bergano 2005 Ibrahim et al. 2002 as well as for routing and switching Lee et al. 2008 Ibrahim et al. 2002 . The motivation for optical technologies is primarily based on the ultrahigh bandwidth of the optical fiber and the extremely low attenuation coefficient. Coupled with minimal pulse distortion properties such as dispersion and nonlinearities optical fibers are the ideal transmission medium to carry information over long distances and to connect optical networks. Unfortunately the adherence of the standard optical fiber to pulse distortions is also what renders it less than perfectly suited for most signal processing applications required in telecommunications. .
