In this paper, we numerically theorize a series of single-mode, dual-mode and three-mode nanophotonic waveguide switches by first combining inverse design algorithm with hybrid silicon-Ge2Sb2Te5 platform. More importantly, these devices realize switching

Design and fabrication of silicon photonic crystal optical waveguides [PDF]
We have designed and fabricated waveguides that incorporate two-dimensional (2-D) photonic crystal geometry for lateral confinement of light, and total internal reflection for vertical confinement. Both square and triangular photonic crystal lattices were analyzed. A three-dimensional (3-D) finite-difference time-domain (FDTD) analysis was used to find

SU-8 Based Waveguide for Optrodes
Neural probes can be equipped with light for optogenetics applications. Different approaches are used for delivering light to the tissue: an optical fiber coupled to the probe, a µLED or a waveguide integrated on the probe.

Numerical Analysis of Multilayer Optical Waveguide Modes based on Effective Refractive Index Method
The effective and efficient refractive index of a multilayer optical waveguide is computed by taking into account the various order modes of the waveguide, such as the Quasi-Transverse Electric/Transverse Magnetic (Quasi-TE/TM) mode.
