Paper Abstract

Photonic crystals (PhCs) have emerged as one of the most significant topics in the field of optical communication since their first introduction by Yablonvitch 1 and John 2. Recently, interest has been grown in the design and development of optical logic gates based on different schemes 3-10. In this paper, we report the design of optical logic AND gate based on two structures, one of which is a hexagonal lattice with silicon (Si) rods in air (SRA) and another is the hexagonal lattice arrangement of air holes in silicon (AHS) with air waveguides. Both the gate structures are based on Y shaped PhC waveguides and analyzed by plane wave expansion (PWE) method. The simulation results show that the proposed structures operates as an AND gates and has a bit rate of 2.016Tbit/s for SRA and 1.785Tbit/s for AHS structure. By appropriately choosing the size and the interaction length of the central rod in SRA and size of central hole in AHS, the optimal performance of the proposed AND logic gates has been achieved.
