Simulation of hybrid silicon nitride/polymer Mach-Zehnder optical modulator beyond 170 GHz

Frontiers in Physics, 2022
In this paper, a hybrid Mach-Zehnder optical modulator is proposed based on silicon nitride/organic polymer waveguides, which is expected to break through the performance bottleneck of the silicon-based optical modulator by exploiting the low-loss ...

Design of Plasmonic NOT Logic Gate Based on Insulator – Metal – Insulator (IMI) waveguides

Advanced Electromagnetics, 2020
In this work, all-optical plasmonic NOT logic gate was proposed using Insulator-Metal-Insulator (IMI) plasmonic waveguides Technology. The proposed all-optical NOT gate is simulated and realized using COMSOL Multiphysics 5.3a software.

Fabrication of Polyimide Optical Waveguide on Silicon Dioxide Layer Stacked Silicon Substrate

Jurnal Elektronika dan Telekomunikasi, 2017
Optical waveguides are important for guiding lightwave from a place to other places. Propagation and insertion losses of the optical waveguides should be considered to be in low values.

Toward Waveguide-Based Optical Chromatography

Frontiers in Physics, 2021
We report analytical expressions for optical forces acting on particles inside waveguides. The analysis builds on our previously reported Fourier Transform method to obtain Beam Shape Coefficients for any beam.

Indium tin oxide overlayered waveguides for sensor applications [PDF]

, 1997
The use of indium tin oxide (ITO) thin films as electrodes for integrated optical electrochemical sensor devices is discussed. The effect of various thicknesses of ITO overlayers exhibiting low resistivity and high transparency on potassium ion-exchanged

Subsurface disorder and electro-optical properties of proton-exchanged LiNbO3 waveguides produced by different techniques [PDF]

Journal of the European Optical Society-Rapid Publications, 2014
It has been established, that proton-exchanged LiNbO3 waveguides have a marked subsurface layer with structural disorder inducing degradation of electro-optical properties of these waveguides.
