- Abstract
In this paper the design and analysis of all optical half adder based on two dimensional photonic crystals is presented. A half adder is a type of adder, an electronic circuit that performs the addition of numbers. The half adder is able to add two single binary digits and provide the output plus a carry value. The proposed structure uses a hexagonal lattice with the point defect based structure. The structural design is small in size and it is compact in nature. These structural analysis of half adder mainly satisfies the logic function as A=1, B=0, A=0, B=1, A=1, B=1. The functional parameters of half adder such as normalized efficiency, bit rate, contrast ratio and the maximum delay time are calculated. The main application of half adder is to compute binary addition operation on two bits in integrated circuits.
