The commercial viability of planar photonic crystals as a platform for photonic integration in telecommunication networks is discussed. We consider the required specifications and the challenges faced by companies intent on commercializing photonic crystal technology.
Optical splitters with high resolution at Y branches have been fabricated through direct photolithography by using photosensitive polysiloxane based materials. The splitters showed low insertion losses with excellent uniformity at 1310 nm and 1550 nm.
