Periodic dielectric waveguides

Optics Communications, 1972
Abstract Dielectric waveguides having periodically corrugated surfaces are analyzed. The analysis shows that scattering occurs when the periodicity is greater than half the free space wavelength.Gap widths are calculated and dispersion diagrams are given. The results are applied to the design of band pass filters and phase-matching devices.

Photoluminescence of Dielectric Waveguides

2020
This chapter overviews the ion-beam-implanted/irradiated dielectric waveguides in view of their applications in photoluminescence. The up-conversion and the near-infrared luminescence processes realized in ion-implanted/irradiated waveguides based on rare-earth-doped crystals and glasses are summarized in Sects. 7.1 and 7.2, respectively.

Efficient dielectric waveguide lasers

2016 18th International Conference on Transparent Optical Networks (ICTON), 2016
In the past decade, rare-earth-doped and also transition-metal-doped dielectric waveguides have emerged as highly efficient laser devices. This paper reviews the results in Ti:Sapphire, polymer, sesquioxides, amorphous aluminium oxide, and potassium double tungstates that have recently been obtained in our research group, partly in collaboration with ...

Time Dispersion in Dielectric Waveguides

Bell System Technical Journal, 1971
In dielectric waveguides operating at optical frequencies, the primary cause of time dispersion of narrow pulses can be mode conversion. In this paper we argue that under certain assumptions a dielectric waveguide acts as a linear system in intensity.

DIELECTRIC-LOADED PLASMONIC WAVEGUIDE COMPONENTS

2011
This chapter concerns modeling, design, and characterization of dielectric-loaded plasmonic waveguide components at telecommunication wavelengths, aimed at establishing a new technology platform for integratable nanophotonic components by combining photonics and electronics on the same chip.

Anisotropic dielectric waveguides

Journal of the Optical Society of America A, 1993
The guided modes of anisotropic waveguides are known to be leaky when degenerate radiation modes of the orthogonal polarization exist. These losses can be quite large when the principal axes of the dielectric tensor are not aligned with the waveguide axis.

Dielectric coaxial waveguide

Journal of Applied Physics, 1973
Modal cutoff, dispersion, and attenuation characteristics for the dielectric coaxial waveguide (three interfaces) are presented for representative parameters. These properties change considerably as the guide geometry and dielectric properties are varied.

Theory of Dielectric Waveguides

1975
Dielectric waveguides are the structures that are used to confine and guide the light in the guided-wave devices and circuits of integrated optics. This chapter is devoted to the theory of these waveguides. Other chapters of this book discuss their fabrication by such techniques as sputtering, diffusion, ion implantation or epitaxial growth.
