چکیده

Silicon based ARROW-A structures have been designed in order to obtain a high sensitive integrated optical transducer for sensing applications. The sensor has a Mach-Zehnder interferometer configuration. The optical waveguides that confonn its structure have to verify two conditions: monornode behaviour and high surface sensitivity. In this paper we present a theoretical simulation of the propagation characteristics and surface sensitivity of the ARROW-A structure. According to the obtained results, several waveguides that verify the rnentioned aboye have been designed and for implementation in the Mach-Zehnder

A 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...
