Estudio y Simulación de los efectos no lineales Scattering Estimulado de Brillouin (SBS) y Scattering Estimulado de Raman (SRS) en una Fibra Óptica Monomodo

Revista Politécnica, 2014
Debido al gran auge de la fibra óptica como medio de transmisión, es imprescindible estudiar los fenómenos no lineales que se producen al propagar una señal luminosa en dicho medio, ya que éstos resultan ser perjudiciales en la transmisión.

Enhanced Stability in Zero‐Excess Li‐Metal Batteries via Prelithiated Carbon Nanofiber Interlayers

Advanced Science, EarlyView.
Carbon nanofibers carbonized at 700°C show Li metal deposition predominantly on the side facing the Cu current collector. During delithiation, Li agglomerates remain as inactive lithium on the fiber surface. This behavior can be changed by a modified n‐Buli prelithiation without a washing step, suppressing dead Li formation and therefore enabling ...

Light amplification and nonlinear microscopy by stimulated raman scattering

, 2016
The Stimulated Raman Scattering has important connections with nanophotonics and biophotonics. Concerning nanophotonics, one of the most recent challenges is the investigation of 'nonlinear optical phenomena at nanoscale'.

Broadband background-free stimulated Raman scattering microspectroscopy with a novel frequency modulation scheme

Stimulated Raman scattering (SRS) microspectroscopy is a powerful imaging technique that leverages chemical composition to produce detailed, label-free images in applications such as biomedical and environmental sciences. However, current SRS methods are

From Label‐Free Multiphoton Imaging to Pathological Reports: A Vision‐Language Breast Cancer Margin Pathological Diagnosis System

Advanced Science, EarlyView.
MarginPath is a novel vision‐language system that automates breast cancer margin assessment using a single label‐free multiphoton microscopy image. By integrating tumor‐associated collagen signatures with virtual H&E imaging, it generates accurate margin heatmaps and comprehensive diagnostic reports.

Raman amplification and pulsed lasing in cladding-pumped germanosilicate fiber

We report for the first time Raman amplification in a cladding-pumped fiber. The double-clad germanosilicate fiber was pumped by a Q-switched Er-Yb co-doped fiber laser at 1570 nm. The power conversion efficiency was up to 36%, with a slope of 64%

Bilateral SERS‐Microneedle Patch for Co‐Diagnosis of Diabetes Mellitus and Tuberculosis Comorbidity

Advanced Science, EarlyView.
Our study introduced a U@mP@Au‐mediated bilateral SERS‐microneedle patch for analyzing glucose levels from ISF and sensitively detecting TB biomarkers from sputum, respectively. This integrated dual‐analyte detecting platform can be used for co‐diagnosis of diabetes mellitus (DM) and tuberculosis (TB) comorbidity, which was demonstrated in ex vivo ...

Polarization Changes of Radiation through Stimulated Raman Scattering

, 1993
We study change in the polarization of electromagnetic waves due to the stimulated Raman scattering in a plasma. In this process an electromagnetic wave undergoes coherent scattering off an electron plasma wave.

Geometry‐Controlled Assembly of Self‐Standing Nanorods With Undisturbed Plasmonics

Advanced Science, EarlyView.
This study reports a geometry‐driven assembly strategy to vertically align Au@Ag core–shell nanorods on PS beads. This well‐defined architecture enables the preservation of the intrinsic optical response of individual nanorods. Thus, demonstrate a highly reproducible SERS enhancement with exceptional uniformity.
