Plasmonic Saturable Absorbers

open access: yesAdvanced Photonics Research, 2021
Plasmonic materials are able to spatially confine light to a nanometer scale far smaller than the diffraction limit, resulting in drastically enhanced electrical field strength and stimulating applications in nonlinear optics, energy, and biomedicine ...

Experimental investigation of cut-off phenomena in non-linear photonic crystal fibers

open access: yes, 2003
The modal cut-off is investigated experimentally in a series of high quality non-linear photonic crystal fibers. We demonstrate a suitable measurement technique to determine the cut-off wavelength and verify it by inspecting the near field of the modes ...

All-Normal Dispersion Hole-Assisted Silica Fibers for Generation of Supercontinuum Reaching Midinfrared

open access: yesIEEE Photonics Journal, 2016
A design of technologically feasible hole-assisted silica fibers with all-normal dispersion was proposed and optimized for maximum dispersion located, respectively, at 1.55 and 1.97 $\mu\text{m} $.

Stochastic solutions to the non-linear Schrodinger equation in optical fiber

open access: yesThermal Science, 2022
The non-linear random Schrodinger equation via geometric distribution and expo?nential distribution is considered. We carry out the unified solver technique to ob?tain some new random solutions. The statistical distributions are utilized to show the dispersion random input.

Raman tailored photonic-crystal-fiber for telecom band photon-pair generation

open access: yes, 2017
We report on the experimental characterization of a novel nonlinear liquid-filled hollow-core photonic-crystal fiber for the generation of photon pairs at telecommunication wavelength through spontaneous four-wave-mixing.

Multiple Microwave Frequency Measurement With Improved Resolution Based on Stimulated Brillouin Scattering and Nonlinear Fitting

open access: yesIEEE Photonics Journal, 2019
A multiple microwave frequency measurement is experimentally demonstrated by exploiting stimulated Brillouin scattering and nonlinear fitting. Through sweeping a reference frequency during the stimulated Brillouin scattering process, the frequency ...

Fast High Resolution Echelle Spectroscopy Of A Laboratory Plasma [PDF]

open access: yes, 2006
An echelle diffraction grating and a multianode photomultiplier tube are paired to construct a high resolution (R=lambda/delta lambda approximate to 2.5x10(4)) spectrograph with fast time response for use from the UV through the visible.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Time Delay Concealment in Feedback Chaotic Systems With Dispersion in Loop

open access: yesIEEE Photonics Journal, 2017
The concealment of time delay signature is one of the most critical issues in delayed-feedback optical chaotic systems. In this paper, we present a method to address this problem without significantly complicating the original architecture.
