On the design of silicon Mach-Zehnder interferometers for the C-band
(Institute of Electrical and Electronics Engineers Inc., 2019)
A silicon Mach-Zehnder interferometer is designed, fabricated and experimentally demonstrated for the C-band. Several interferometers were designed with different free spectral ranges. The influence of the waveguide width ...
Double optical monitoring of time-dependent film formation
(2005-12-23)
A brief overview of optical monitoring for vacuum and wet bench film deposition processes is presented. Interferometric and polarimetric measurements are combined with regard to simultaneous real-time monitoring of refractive ...
Lead-germanate glasses and fibers: A practical alternative to tellurite for nonlinear fiber applications
(2013-09-20)
We report on the fabrication of novel lead-germanate glasses and fibers. We have characterized these glasses in terms of their thermal properties, Raman spectra and refractive indices (both linear and nonlinear) and present ...

Finite element analysis of anisotropic optical waveguide with arbitrary index profile
(1999-12-01)
This work presents the application of a scalar finite element formulation for Ex (TE-like) modes in anisotropic planar and channel waveguides with diagonal permittivity tensor, diffused in both transversal directions. This ...

Method for real-time measurement of the nonlinear refractive index
(American Institute of Physics, 2019-09)
In this work, we propose a novel method for continuous real-time measurement of the dynamics of the nonlinear refractive index n2. This is particularly important for characterizing phenomena or materials (such as biological ...
Thermal tunability of photonic bandgaps in photonic crystal fibers selectively filled with nematic liquid crystal
(2010-12-01)
We address the bandgap effect and the thermo-optical response of high-index liquid crystal (LC) infiltrated in photonic crystal fibers (PCF) and in hybrid photonic crystal fibers (HPCF). The PCF and HPCF consist of solid-core ...
