چکیده
In this paper, an optical half adder is designed using photonic crystals. One of the features its small size. design structure, it has been tried to have a size, shorter delay and high contrast ratio so that can be used in integrated circuits. For sum carry outputs, obtained 15.4 dB 7.4 dB, respectively. addition, proposed structure size 70 µm2. The use simple point defects, caused maximum time reduced 0.07 ps. Due these characteristics, suitable for high-speed

متن کاملAll-photonic molecular half-adder.
One molecule acts as both an AND and an XOR Boolean logic gate that share the same two photonic inputs. The molecule comprises a half-adder, adding two binary digits with only light as inputs and outputs, and consists of three covalently linked photochromic moieties, a spiropyran and two quinoline-derived dihydroindolizines. The AND function is based on the absorption properties of the molecule...

متن کاملFast Mux-based Adder with Low Delay and Low PDP
Adders, as one of the major components of digital computing systems, have a strong influence on their performance. There are various types of adders, each of which uses a different algorithm to do addition with a certain delay. In addition to low computational delay, minimizing power consumption is also a main priority in adder circuit design. In this paper, the proposed adder is divided into s...
