Birefringence analysis of multilayer leaky cladding optical fibre [PDF]
, 2010 We analyse a multilayer leaky cladding (MLC) fibre using the finite element method and study the effect of the MLC on the bending loss and birefringence of two types of structures: (i) a circular core large-mode-area structure and (ii) an elliptical ...

Considerations of Curvature for a Near-Eye Holo-Video Display
Applied Sciences, 2020 Most 3D augmented reality, near-eye displays suffer from a low field of view. Leaky-mode lithium niobate devices are often used to steer, multiplex, or otherwise control the path of light in a system.

Novel Selected Modes on the Conductor - Backed Slotline [PDF]
, 2002 This paper presents a detailed full-wave analysis of the conductor-backed slotline. The occurrence of an even dominant mode is revealed. This mode may propagate alone from dc up to the frequency at which the first leaky mode sets up.

Co-axial dual-core resonant leaky fibre for optical amplifiers [PDF]
, 2008 We present a co-axial dual-core resonant leaky optical fibre design, in which the outer core is made highly leaky. A suitable choice of parameters can enable us to resonantly couple power from the inner core to the outer core. In a large-core fibre, such

Resonant State Spectral expansions including bound-state contributions [PDF]
EPJ Web of Conferences, 2023 Extensions of the Resonant State or (Quasi-normal mode) formalism are shown to permit unified descriptions of the true ’bound’ states within the framework of the ’leaky’ mode formulation of basis sets.

Low-frequency excitation of leaky modes in a microstripline with a top cover [PDF]
, 2011 This paper studies the excitation of a physical leaky mode in a covered microstrip structure at low frequencies. We calculate the current excited in the line by a delta-gap voltage source via a full wave analysis based on a mixed potential integral ...

Static Structures in Leaky Mode Waveguides
Applied Sciences, 2019 In this work, we suggest a new method of expanding the field of view in bottom-exit, leaky mode devices for transparent, monolithic, holographic, near-eye display.

IEEE Access, 2023 A rectangular metallic leaky waveguide loaded with liquid crystals (LC) and operating in its fundamental TE mode at 1 THz is proposed to mitigate the well-known trade-off between directivity and tunable angular range of dynamic beamscanning antennas. The
