Compact Optical Waveguides Based on Hybrid Index and Surface-Plasmon-Polariton Guidance Mechanisms

open access: yesActive and Passive Electronic Components, 2007
Surface-plasmon-polariton (SPP) waveguides made of materials available in nature have, in general, been found to suffer from very high absorption loss when light confinement is beyond diffraction limit.

Experimental Verification of Degenerate Band Edge Dispersion in Silicon Photonic Integrated Circuits

open access: yesIEEE Photonics Journal, 2016
On resonance, periodic dielectric media of finite length exhibit large and distributed internal electric field distributions. The large and distributed fields have been exploited for applications in light emission, optical switching, and nonlinear optics.

Low-loss singlemode PECVD silicon nitride photonic wire waveguides for 532-900 nm wavelength window fabricated within a CMOS pilot line [PDF]

open access: yes, 2013
PECVD silicon nitride photonic wire waveguides have been fabricated in a CMOS pilot line. Both clad and unclad single mode wire waveguides were measured at lambda = 532, 780, and 900 nm, respectively. The dependence of loss on wire width, wavelength, and

Propagation Losses of Slotted Photonic Crystal Waveguides

open access: yesIEEE Photonics Journal, 2012
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

open access: yesIEEE Photonics Journal, 2013
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 ...

Diamond photonics platform enabled by femtosecond laser writing [PDF]

open access: yes, 2016
We demonstrate the first buried optical waveguides in diamond using focused femtosecond laser pulses. The properties of nitrogen vacancy centers are preserved in the waveguides, making them promising for diamond-based magnetometers or quantum information
