2.CONCEPT OF OPTICAL LOGIC GATE
3.PHOTONIC CRYSTAL
Photonic crystals are microscopically structured materials, whose unique properties have changed our view of optics and opened up new ways of processing light.
Photonic crystals are composed of periodic dielectric or metallo-dielectric nanostructures that affect the propagation of electromagnetic waves (EM) in the same way as the periodic potential in a
Semiconductor crystal affects the electron motion by defining allowed and forbidden electronic energy bands. Photonic crystals contain regularly repeating regions of high and low dielectric constant.
4.Technology
Photonic crystals are based on silicon-compatible materials and can be processed using technology that is already being employed on a daily basis by the semiconductor industry. Here at Photon Technologies, our research is focused on planar and two-dimensional photonic crystal structures. Which can be manufactured from conventional SOI substrates or integrated into multi-layer structures.

6.Y-DEFECT PHOTONIC CRYSTAL
By implementing line defect we have realized some of the logic gates based on photonic crystals. Also Yu Lee has designed a 4x2 encoder by V-defect.
7.Y-Defect Photonic Crystal for OR Logic
8.OPTICAL RESONATOR
An optical cavity or optical resonator is an arrangement of mirrors that forms a standing wave cavity resonator for light waves. Optical cavities are a major component of lasers, surrounding the gain medium and providing feedback of the laser light.
