Calculation of Fundamental Mode Properties for Single-Mode Fibers

Tikrit Journal of Pure Science, 2021
In this research, properties for the fundamental mode of single-mode step-index optical fibers with core diameters 9.8–15.6 µm, core refractive index  and cladding refractive index  are calculated at a wavelength of 1.55 µm by using RP Fiber Calculator ...

The ICON Single-Column Mode

Atmosphere, 2021
The single-column mode (SCM) of the ICON (ICOsahedral Nonhydrostatic) modeling framework is presented. The primary purpose of the ICON SCM is to use it as a tool for research, model evaluation and development.

Effect of many weak side modes on relative intensity noise of distributed feedback semiconductor lasers [PDF]

, 1998
An increase of the relative intensity noise of nearly single-mode distributed feedback lasers with respect to that predicted by single-mode theory after propagation in dispersive fiber at frequencies up to 5 Ghz has been measured.

Surface enhanced Raman spectroscopy on single mode nanophotonic-plasmonic waveguides [PDF]

, 2016
We analyze the generation of Surface Enhanced Raman Spectroscopy signals from integrated bowtie antennas, excited and collected by a single mode silicon nitride waveguide, and discuss strategies to enhance the Signal-to-Noise ...

Single-Mode Tapered Vertical SU-8 Waveguide Fabricated by E-Beam Lithography for Analyte Sensing

Sensors, 2019
In this paper, we propose a novel vertical SU-8 waveguide for evanescent analyte sensing. The waveguide is designed to possess a vertical and narrow structure to generate evanescent waves on both sides of the waveguide’s surface, aimed at ...

Mode Transforming Properties of Tapered Single-Mode Fiber Microlenses [PDF]

, 1993
The Gaussian approximation that is typically used to estimate single-mode fiber microlens performance is investigated. It is applied to hemispheric lenses on two types of tapered single-mode fiber. Theoretical and experimental results are compared.

Fluctuations relations for semiclassical single-mode laser

, 2008
Over last decades, the study of laser fluctuations has shown that laser theory may be regarded as a prototypical example of a nonlinear nonequilibrium problem.
