Birefringence effects in fibre-based polarisation-insensitive FWM systems [PDF]

, 2022
We present a quantitative study of the effects of birefringence in polarisation-insensitive orthogonal-pump four-wave mixing (FWM) systems, that ultimately advises on appropriate fibre length selection for minimised polarisation dependent ...

Four-Wave-Mixing in Zirconia-Yttria-Aluminum Erbium Codoped Silica Fiber [PDF]

Journal of the European Optical Society-Rapid Publications, 2012
The generation and characterization of the Four-Wave-Mixing (FWM) effect in an Erbium Doped Zirconia-Yttria-Alumino Silicate Fiber (EDZF) is described. The EZDF is fabricated from a conventional silica preform by Modified Chemical Vapour Deposition (MCVD)

Functional tooth unit, periodontal status, and association with weight change in older adults

Journal of Periodontology, EarlyView.
Abstract Background Literature reports that having fewer teeth is associated with reduced chewing capacity, which in turn may lead to weight changes due to diminished oral functionality. This study aims to assess the association between functional tooth units (FTU) and periodontal status and weight change among older adults participating in the Health,

FWM-Minimizing Channel Allocation Algorithmic Scheme for Multichannel DWDM Transmission System

, 2017
In this paper, we propose a novel channel allocation scheme, i.e., the asymmetrically paired repeated unequally spaced (APRUS) scheme, for the dense wavelength division multiplexing (DWDM) transmission system.

Food waste management in the hospitality sector: a systematic review of the strategies and barriers

Frontiers in Sustainability
The hospitality industry is a major source of food waste (FW) worldwide. This makes it harder to achieve global development goals such as SDG 2 (ending hunger), SDG 12 (responsible consumption and production), and SDG 13 (climate action).

Broadband Parametric Amplification in AlGaAs‐on‐Insulator Nanowaveguides

Laser &Photonics Reviews, EarlyView.
Harnessing the exceptional nonlinearity of AlGaAs‐on‐insulator nanowaveguides, four‐wave‐mixing parametric amplification achieves a record net on‐chip gain of 56 dB and a gain bandwidth exceeding 415 nm at telecom wavelengths. These results establish AlGaAsOI as a powerful platform for compact, high‐performance integrated nonlinear optical ...
