In this chapter, after presenting a brief review of the various types of optical waveguides, we outline the key principles and parameters which describe and define the operation of optical waveguides and fibres. The ways in which propagation through optical fibres affects the properties of the guided waves are discussed, including dispersion and non ...

PHASE COHERENCE OF OPTICAL WAVEGUIDES
Integrated Photonics Research, 1993By measuring null wavelengh fluctuations of Mach Zehnder interferometers of different order we verify a proposed random walk model for accumulating phase in optical waveguides. A coherence length equal to ≈27M was found to characterize our silica on silicon waveguides.

Optical waveguide cable connection
Applied Optics, 1976The requirements for a practical optical waveguide cable connector are reviewed. The sources of loss in fiber-to-fiber coupling, both intrinsic (fiber-related) and extrinsic (connector-related), are discussed and quantified. A multiple channel, single-fiber-per-channel connector concept, termed the overlap connector, is then described, with emphasis on

Single-mode optical waveguides
Applied Optics, 1979An efficient and powerful technique has been developed to treat the problem of wave propagation along arbitrarily shaped single-mode dielectric waveguides with inhomogeneous index variations in the cross-sectional plane. This technique is based on a modified finite-element method.

Waveguides and fibers for nonlinear optics
Journal of the Optical Society of America B, 1988Optical waveguides are ideal for nonlinear interactions because they provide strong beam confinement over long propagation distances. They are characterized by regions of high refractive index bounded by regions of lower refractive index. Examples of such waveguides are shown in Figure 1.

Statistics of backscattering in optical waveguides
Optics Letters, 2010The statistics of backscattering induced by sidewall roughness in dielectric optical waveguides is experimentally investigated. We demonstrate that waveguide backscattering is a wavelength-dependent random process, whose statistics follows the rules of single scattering systems, independently of shape, size, and refractive index contrast of the ...

Optical similaritons in nonlinear waveguides
Optics Letters, 2007We discover analytically an extensive family of optical similaritons, propagating inside graded-index nonlinear waveguide amplifiers. We show that there exists a one-to-one correspondence between these novel similaritons and standard solitons of the homogeneous nonlinear Schrödinger equation.

Optical strip waveguide: an analysis
Applied Optics, 1979An analysis of the strip waveguide is presented with special emphasis on reflection and transmission of a wave obliquely incident on the side of a strip. Mode conversion and the contribution of radiation modes are taken into account in the formulation.

Waveguide dispersion in anisotropic optical waveguides
Soviet Journal of Quantum Electronics, 1987The method of shift formulas is employed to obtain approximate analytic expressions which can be used to calculate?with sufficient accuracy for practical applications?the waveguide and polarization dispersion of the dominant orthogonally polarized modes in anisotropic optical fiber waveguides.
