Summary The challenges for introducing optical waveguides into the high performance computer packaging environment are formidable. Polymers may be well suited for meeting this challenge. In this work, progress was shown using an epoxy material vT hich has been fabricated into ridge waveguides which exhibit low propagation loss (0.3 dB/cm at 1.3 jum ...

A novel optical waveguide for integrated optics
IEEE Journal of Quantum Electronics, 1973A novel dielectric optical waveguide was made consisting of a guide pattern on a thin dielectric film. Almost all the power propagates in the thin film along the guide pattern. The existence of propagation modes of this waveguide was verified both theoretically and experimentally.

Optical Waveguide Refractometers
2005In this chapter we have illustrated a new method for the determination of the refractive index of liquid samples, based on Cerenkov second harmonic generation from suitable planar waveguides. The method allows the determination of the refractive index in the near infrared by detection in the visible.

Nonorthogonal Optical Waveguides and Resonators
Bell System Technical Journal, 1970The modes of propagation in optical systems which do not possess meridional planes of symmetry (nonorthogonal systems) are investigated in the case where the effect of apertures and losses can be neglected. The fundamental mode of propagation is obtained with the help of a complex ray pencil concept.

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 ...
