Abstract In this paper, we introduce simple design equations for optical phase shifter configurations on both single mode and multimode platforms. The are based approximate analytical expressions describing the shift (difference) between two waveguides, one is considered as reference guide second shifter. Different layout geometrical have been studied: step width linear tapering waveguide. vali...

Herein, the mid-infrared (7.7–13.7 ?m) diamond-based phase shifter was designed and optimized by finite-element analysis. The ridge-shaped diamond waveguide is doped to form internal p–n structure, carrier distribution changed applying forward reverse voltages change effective refractive index achieve effect of ?-phase shift. results show that when p-doping concentration 4 × 1017 cm?3 n doping ...

This article presents a novel method for the forward modeling and inverse design of class Schiffman phase shifters using deep neural networks (DNNs). Since DNNs are capable mapping highly nonlinear correlations between inputs outputs, we constructed fully connected DNN to predict electromagnetic (EM) responses given their physical dimensions. Based on this fast accurate tool, cascaded was then ...

The phase of terahertz waves can now be precisely modulated electronically using a chip-based digitally coded shifter. achievement is step towards chip-scale integrated technology.
