Optical Logic Devices Based on Photonic Crystal for Telecommunication Applications

Semiconductor materials and devices have always dominated the world of electronics in the form of gates, diodes, transistors, etc. In today’s world rapidly growing technologies we require advancements in every field specially electronics. So we move in the context of this advancement form electronics to the world of optics. Our effort through this work is to make the semiconductor devices work in the optical field. Hence, we use the most promising optical structure of photonic crystals by implementing optical logic gates instead of analytical electronic gates. Optical components that permit the miniaturization of photonic integrated circuits to a scale comparable to the wavelength of light are good candidates for future optical network and optical computing. All-optical communication is one of the solution for the electronic bottleneck viz speed and size, thanks to their ability to process the information at the speed of light. Optical logic gates are the fundamental components in optical digital information processing.
