Leaky mode integrated optical fibre refractometer
Optics Express, 2018 A route to monitor external refractive indices greater than the core index of the waveguide is presented. Initial application utilizes an integrated optical fibre (IOF) platform due to its potential for use in harsh environment sensing. IOF is fabricated using a bespoke flame hydrolysis deposition process to fuse an optical fibre to a planar substrate ...

Photonic-plasmonic mode coupling in nanopillar Ge-on-Si PIN photodiodes
Scientific Reports, 2021 Incorporating group IV photonic nanostructures within active top-illuminated photonic devices often requires light-transmissive contact schemes. In this context, plasmonic nanoapertures in metallic films can not only be realized using CMOS compatible ...

Leaky modes in multilayer uniaxial optical waveguides [PDF]
Applied Optics, 1990 The propagation characteristics of the leaky modes in planar anisotropic waveguides with a multilayer structure have been investigated by means of a compact rigorous formalism. The leakage losses and leaky transition angle have been studied for the fundamental and first hybrid modes.

Visualization of leaky waves on planar transmission lines [PDF]
, 2004 This paper presents a visualization of leaky waves excited by delta-gap sources on planar transmission lines, namely the 2nd surface and space leaky modes on the slotline, and the dominant and surface leaky modes on the conductor-backed slotline.

Angular control of anisotropy-induced bound states in the continuum [PDF]
, 2019 Radiation of leaky modes existing in anisotropic waveguides can be cancelled by destructive interference at special propagation directions relative to the optical axis orientation, resulting in fully bound states surrounded by radiative modes.

Analysis of Leaky Modes in Photonic Crystal Fibers Using the Surface Integral Equation Method
Crystals, 2018 A fully vectorial algorithm based on the surface integral equation method for the modelling of leaky modes in photonic crystal fibers (PCFs) by solely solving the complex propagation constants of characteristic equations is presented.

Higher-Order Leaky-Mode Bessel-Beam Launcher [PDF]
IEEE Transactions on Antennas and Propagation, 2016 We present a Bessel-beam launcher based on a leaky radial waveguide consisting of a capacitive sheet over a ground plane that supports higher-order leaky modes. A propagating Bessel beam is generated above the radiating waveguide. The Bessel beam is transverse-magnetic (TM) polarized with a vertical component of electric field that is a zeroth-order ...
