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.

Microwave Complex Permittivity of Yttria-Stabilized Zirconia
IEEE Open Journal of Instrumentation and Measurement, 2023 The complex permittivity of 8-mol yttria-stabilized zirconia (8-YSZ) in powder and sintered (i.e., solid) forms were measured from 32 to 40 GHz using a circular waveguide probe.

Tapered depressed-cladding waveguide lasers modulated by Ag nanoparticles embedded in SiO2
Results in Physics, 2021 We report on fabrication of tapered circular depressed-cladding waveguides in Nd:YAG crystal by femtosecond laser direct writing (FsLDW). Based on the fabricated waveguides, for the first time to the best of our knowledge, efficient Q-switched mode ...

All-Optical Bistability in Photonic Crystal Slabs with Coupled Cavity-waveguide Structure [PDF]
فیزیک کاربردی ایران, 2021 In this study, we consider a photonic crystal slab with a triangular lattice, which consists of air holes with a circular shape in a tellurium background on top of a Teflon substrate.

Modeling and Simulation of stochastically deformed Waveguides using Schelkunoff's Method [PDF]
Advances in Radio Science, 2018 This paper deals with the propagation of electromagnetic waves in cylindrical waveguides with irregularly deformed cross-sections. The general theory of electromagnetic waves is of high interest because of its practical use as a transmission medium ...

Using quasi-guided modes for modeling the transfer behavior of bent dielectric slab waveguides [PDF]
Advances in Radio Science, 2010 The connection of two straight dielectric multimode slab waveguides by a circular bent waveguide is analyzed by means of quasi-guided modes. These modes correspond to the well known leaky modes, but own real eigenvalues, thus the mathematical ...
