Propagation Losses of Slotted Photonic Crystal Waveguides
We have fabricated and characterized a set of slotted photonic crystal (SPhC) waveguides in silicon-on-insulator (SOI) with a length of up to 300 $\mu\hbox{m}$ and slot widths ranging between 115 and 145 nm.

TE/TM-Pass Polarizer Based on Lithium Niobate on Insulator Ridge Waveguide
We propose a TE/TM-pass polarizer based on a shallow X-cut lithium niobate-on-insulator (LNOI) ridge waveguide. In shallow X-cut LNOI ridge waveguides, the leaky mode is interchanged between TE and TM polarization waves depending on the ridge waveguide ...

Understanding the rich physics of light propagation in slow photonic crystal waveguides [PDF]
Selected papers. Held as part of SPIE Photonics West 2010.We study propagation losses in slow light photonic crystal waveguides and show that dispersion engineering can reduce the loss.

Indium tin oxide overlayered waveguides for sensor applications [PDF]
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

Sub‐THz Phase Shifters Enabled by Photoconductive Single‐Walled Carbon Nanotube Layers
Materials with tunable dielectric properties are highly relevant for terahertz (THz) applications. Herein, the tuning of the dielectric response of single‐walled carbon nanotube layers by light illumination is studied for applications to THz phase ...
