چکیده
Optical half subtractors are required for designing any optical computation system. Operation speed and the on/off contrast ratios very important characteristics logic device. A novel structure composed of three nonlinear ring resonators some waveguides used proposed subtractor with improved operation ratio. The simulation results show that rise time this is 1.5 ps. Also B D 13.7 dB 14.5 respectively.

Ultra-Fast All-Optical Half Subtractor Based on Photonic Crystal Ring Resonators
Abstract: In this paper, we aim to design and propose a novel structure for all-opticalhalf subtractor based on the photonic crystal. The structure includes two optical switches,one power splitter, and one power combiner. The optical switches are made of theresonant rings which use the nonlinear rods for dropping operation. The footprint of thedesigned structure is about...
متن کاملA New Proposal for 4-to-2 Optical Encoder Using Nonlinear Photonic Crystal Ring Resonators
In this paper, we proposed an all optical 4-to-2 encoder that has 4 input and 3 output ports. This device generates a 2 bit binary code based on which input port is active. We used nonlinear photonic crystal ring resonators along with optical power splitter for realizing the proposed encoder. In this device the switching rate and area are obtained about 333 GHz and 612µm2 respectively.
متن کاملAll-Optical Ultra compact Photonic Crystal Switch Based on Nonlinear Micro Ring Resonators
In this paper an all-optical switch has been proposed based on photonic crystal T-type ring resonator. The finite different time domain (FDTD) and plane wave extended (PWE) methods are used to analyze the behavior of the structure. The T-type ring resonator has a low switching time of about 0.95ps and low switching power equal to 156mW/μm 2 . Since the structure has a simple geometric shape wit...
متن کاملA novel design for all-optical NAND/NOR/XOR gates based on nonlinear directional coupler
In this paper a novel all-optical logic NAND, NOR and XOR gate based on nonlinear directional coupler theory is demonstrated. We use the identical structure which contains three waveguides, for designing these gates; the only difference however, is the power of inputs light beam. In other words, while a beam with 4 W/μm in power considered as logical one, the output is NAND gate and if a beam w...
