High data-rate two-three inputs all-optical AND gate based on FWM in highly nonlinear fiber

Abstract

In this paper, two-and-three channel all-optical AND logic gates based on four-wave mixing in a highly nonlinear fiber for 120 Gbps on–off keying signals were designed, simulated, and investigated. Simulation results show low bit error rate and consequently fairly high Q-factor at the receiving end in both two and three inputs AND gates, as well as the logic operation, is confirmed by the open eye diagrams with moderate power penalties for both designs.

Design of Ultrasmall Plasmonic Logic Gates Based on Single Nanoring Dielectric-Metal-Dielectric Waveguide

“…Control of the constructive and destructive interferences between light signals in plasmonic waveguides is the basic idea for designing plasmonic devices [2][3][4][5]. In recent years, many passive and active SPP devices such as switches [6,7], logic gates [5,[8][9][10][11][12][13][14][15][16][17][18], sensors [19,20], nanowires [21][22][23], splitters [24], flters [25,26], couplers [27], resonators [28,29], and multi-and demultiplexers have been designed [30][31][32][33]. In design of plasmonic logic gates, DMD [14,[34][35][36] and metal-dielectric-metal (MDM) plasmonic waveguides are mostly used [37][38][39][40][41][42][43][44].…”

Design and implementation of PC to PC data transmission using wireless visible light communication system

“…Light-emitting diodes (LEDs) may turn on and off quickly. LEDs can send binary data at fast speeds [9]. Using a powerful laser, it will be feasible to communicate by using the satellite to reflect the signal that the laser beam can emit in a variety of wavelengths from ultraviolet to infrared areas.…”
