Il y a 1 jour · Abstract We report in this work the numerical study of the supercontinuum phenomenon raised from Airy pulses within a silicon-on-insulator waveguide including loss effects, third-harmonic generation (THG) and negative-frequency Kerr (NFK) terms. This study is conducted through a modeling based on the full unidirectional pulse propagation equation model which allows to assume the existence of ...
25 juin 2024 · With dispersion engineering, optimizing waveguide geometry, and pumping by a multi-wavelength femtosecond soliton fiber laser, we achieved a flat-top supercontinuum generation spanning from 1290 to 2400 nm and beyond . It has a 3 dB bandwidth of 436 nm and a 20 dB bandwidth of more than 900 nm.
11 juin 2024 · Abstract: The high-intensity cascaded Raman peaks and low-intensity short wavelength components are two bottle-neck factors that limit the further spectrum flatness improvement of supercontinuum (SC) in the broadband range. In this paper, we address these challenges by introducing a dual-wavelength pumping scheme based on enhanced ...
