Abstract Waveguides are basically a device (‘a guide’) for transporting electromagnetic energy from a source to another defined point, through a structure that is invariant in one or two directions without any loss in wave intensity. The chapter is intended to provide an introductory self-contained treatment of optical waveguide theory ...

We propose a fiber structure based on a single-mode-multimode-single-mode one. A theoretical analysis model based on leaky mode expansion along with a new concept of leaky mode interference is presented to facilitate and enlighten the analysis for the leaky structure.

Abstract A liquid level sensing scheme based on leaky mode attenuation and a corresponding liquid level sensor based on a guided-mode–leaky-mode–guided-mode (GLG) fiber structure are proposed, which aim at the liquid whose refractive index (RI) is higher than that of the silica fiber.

Leaky Modes of Symmetrical Groove Guide
MTT-S International Microwave Symposium Digest, 2005Both the odd and even higher modes of groove guide, a low-loss waveguide proposed some years ago for millimeter wavelengths and of interest again today, are investigated quantitatively. We verified an early prediction that all the odd higher modes leak, and we find that all even higher modes do also.

Guided modes in nonlinear periodic structures
IEE Proceedings J Optoelectronics, 1992The formation of optical Bragg waveguides in stratified media possessing a Kerr-type nonlinearity is examined. This is achieved by considering Jacobi elliptic functions matched to decaying Bloch wave solutions. It is shown that above a threshold power guided mode solutions exist whose field confinement is a function of the total guided power. >

Nonpolarizing guided-mode resonance filter
Optics Letters, 2009A normal-incidence nonpolarizing guided-mode resonance filter is designed. There are two waveguide layers and one grating layer in the filter. By adjusting the distance between the two waveguide layers, the same resonance wavelength for both TE and TM polarization can be achieved.

Guided modes in periodical arrays of waveguides
2018 20th International Conference on Transparent Optical Networks (ICTON), 2018Optical waveguides are constituents of various optoelectronic devices. Generally, the interaction between the waveguides brings parasitic impact. However, in several cases the interaction can generate effects useful for applications and simulation of the optical phenomena which have analogues in solid state physics.

Interface characterization by true guided modes
NDT & E International, 1991Guided acoustic waves along interfaces are especially sensitive to specific properties associated with boundary conditions and bond quality since their energy is effectively confined to the region of interest. On the other hand, this inherent advantage turns out to be a significant drawback for generation and detection of such guided waves.

Guided modes in a uniaxial multilayer
Journal of the Optical Society of America A, 2003An algorithm is presented for simulation of guided modes in a multilayer uniaxial structure with each layer characterized by its own ellipsoid of refractive indices and direction of optical axis. The proposed approach is based on presenting an electromagnetic field in each layer as a linear combination of ordinary and extraordinary waves coupled ...
