Understanding leaky modes: slab waveguide revisited
Advances in Optics and Photonics, 2009 Computational methods for determining the complex propagation constants of leaky waveguide modes have become so powerful and so readily available that it is possible to use these methods with little understanding of what they are calculating.

Quasi-bound states in the continuum driven photoresponse in multiple quantum wells for machine vision [PDF]
Light: Science & ApplicationsBound states in the continuum (BIC) leverage symmetry-protected resonant modes for exceptional light confinement, yet their leaky modes are almost underutilized.

Modelling Leaky Waves in Planar Dielectric Waveguides [PDF]
EPJ Web of Conferences, 2020 Experimentally observed leaky modes of a dielectric waveguide are characterised by a weak tunnelling of the light through the waveguide and its long-time propagation along the waveguide.

Status of Leaky Mode Holography [PDF]
Photonics, 2021 It will soon be a decade since leaky mode waveguide devices were presented as a solution for holographic video displays. This paper seeks to provide a brief, topical review of advances made during that time. Specifically, we review the new methods and architectures that have been developed over this period. This work draws primarily from papers seeking

Spontaneous Emission in Leaky Modes of Nanowires
Semiconductors, 2022 Analytical expressions for spontaneous emission pro-bability in the vicinity of nanowire for the emitter oriented in axial, radial and azimuthal direction in respect to the nanowire axis, has been obtained. Directionality of emission and probability of emission have been calculated for various positions of emitter.

Large Mode Area Single Mode Fiber with a Twisted Polygon-Shaped Core
Photonics, 2022 We present numerical studies on twisted polygon-shaped core fibers for achieving single mode operation with a large mode area propagation in this paper. These large mode area fibers can achieve single mode operation due to twisting-induced high losses to
