Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, Volume 38, Issue 51, 11 September 2026.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Modelling and analysis of modal behaviour in SOI slot waveguides

open access: yes, 2008
Mode behaviour for SOI slot waveguides is modelled and analysed using a numerical full vectorial method based on the film mode matching method (MMM). Only the quasi-TE mode is investigated. Waveguide heights and slot widths, as well as silicon widths are

Optical slot antennas and their applications to photonic devices

open access: yesNanophotonics, 2018
We present optical slot antennas and their applications to photonic devices. We show that metallic nanoslots have the properties of a slot antenna by measuring the transmission spectra and far-field radiation patterns and then prove that they can be ...

Design Low Crosstalk Ring-Slot Array Structure for Label-Free Multiplexed Sensing

open access: yesSensors, 2014
We theoretically demonstrate a low crosstalk ring-slot array structure used for label-free multiplexed sensing. The proposed sensors array is based on an array of three ring-slot and input/output line defect coupling waveguides. Each ring-slot cavity has

Nonresonant Magnetic Flux Control Enabling Low‐Loss Epsilon‐Near‐Zero Cavity Antennas

open access: yesAdvanced Photonics Research, Volume 7, Issue 9, September 2026.
Can photonic doping be achieved without resonance? A passive metallic inclusion is shown to engineer effective permeability in epsilon‐near‐zero cavity antennas through magnetic‐flux exclusion, reproducing the response of resonant photonic dopants while reducing losses and providing a unified perspective on photonic doping.

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.

Effects of opto-geometric parameters to enhance field confinement at air-slot waveguides

open access: yes, 2015
In this work, we propose a detailed study of the slotted optical waveguides. The small size of the slot region enables to confine light at sub-wavelength region.
