Design and Simulation of Low-Threshold Miniaturized Single-Mode Nanowire Lasers Combined with a Photonic Crystal Microcavity and Asymmetric Distributed-Bragg-Reflector Mirrors

open access: yesNanomaterials, 2020
A low-threshold miniaturized single-mode nanowire laser operating at telecommunication wavelengths was proposed and simulated. The device was constructed by combining a single InGaAs nanowire with a photonic crystal microcavity and asymmetric distributed-

Optical fiber flowmeter based on a single mode-multimode-single mode structure

open access: yesFrontiers in Sensors, 2022
Single mode-Multimode-Single mode (SMS) sensors have been attracted a relevant attention because of their simple manufacturing, their capability of sensing different quantities, and their enhanced sensitivity compared to the most common fiber optic ...

Single mode and polarization independence in the strained silicon-on-insulator rib waveguides [PDF]

open access: yesHemijska Industrija, 2008
In this paper we investigate the most popular silicon waveguide structures in the form of a silicon-on-insulator (SOI) rib waveguide. Single mode and birefringence free conditions in these relatively small waveguides are discussed and the influence of ...

Stable Multi-Wavelength Thulium-Doped Fiber Laser With Two Cascaded Single-Mode-Four-Mode-Single-Mode Fiber Interferometers

open access: yesIEEE Access, 2021
We propose and experimentally demonstrate a multi-wavelength thulium-doped fiber laser using two cascaded single-mode-four-mode-single-mode (SFS) fiber interferometers and a 150-m-long highly nonlinear fiber.

Large Mode Area Single Mode Fiber with a Twisted Polygon-Shaped Core

open access: yesPhotonics, 2022
We present numerical studies on twisted polygon-shaped core fibers for achieving single mode operation with a large mode area propagation in this paper. These large mode area fibers can achieve single mode operation due to twisting-induced high losses to

Sensing properties of graphene-oxide-functionalized single-mode–no-core–single-mode fiber structure

open access: yesResults in Physics, 2021
A series of single-mode–no-core–single-mode (SNS) optical fiber sensing structures with different thicknesses of graphene oxide (GO) coating were fabricated and tested with glycerin and magnetic fluid solutions.

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

open access: yes, 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.

Single-Mode Phononic Wire

open access: yesPhysical Review Letters, 2018
Photons and electrons transmit information to form complex systems and networks. Phonons on the other hand, the quanta of mechanical motion, are often considered only as carriers of thermal energy. Nonetheless, their flow can also be molded in fabricated nanoscale circuits.

Zero-mode dispersion in single-mode fibres [PDF]

open access: yesElectronics Letters, 1978
Near cutoff the loss of the LP11, mode in cladded optical fibres becomes very high in the presence of even slight bends. Single-mode operation can thus be achieved with zero-mode dispersion as well as zero material dispersion, thus promising enormously large bandwidths.

Calculation of Fundamental Mode Properties for Single-Mode Fibers

open access: yesTikrit 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 ...
