STUDY OF 2D PHOTONIC BANDGAP JUNCTIONS FOR ITS APPLICATION IN ALL OPTICAL COMMUNICATION

Abstract

All-optical signal processing is a promising technology for future optical transparent networks for its strong
abilities to overcoming the electronics bottlenecks, supporting the ultra-fast optical signal processing without requiring
costly optical-electrical-optical equipment. Photonic crystals are potentially very attractive for on chip all optical
communication and highly advantageous in telecommunication due to smaller dimensions. In this paper, the PBG
(Photonic band gap) junctions made by 2D (two dimensional) photonic crystal slab with junction formed due to two
different types of lattices i.e. two different lattice constant of same material are studied and their utilization as optical
buffer is analysed.
