Dispersion Measurement of Ultra-High Numerical Aperture Fibers covering Thulium, Holmium, and Erbium Emission Wavelengths

open access: yes, 2018
We present broadband group velocity dispersion (GVD) measurements of commercially available ultra-high numerical aperture fibers (UHNA1, UHNA3, UHNA4, UHNA7 and PM2000D from Coherent-Nufern). Although these fibers are attractive for dispersion management

Intelligent Stain‐Free Histology on Structural Colorimetric Nanocavities

open access: yesAdvanced Science, EarlyView.
Chen and Gan et al. introduce a label‐free imaging platform using inexpensive Nanocavity‐on‐Silicon (NOS) slides. These slides transform subtle tissue variations into vivid structural colors, enabling high‐contrast histological imaging under a regular optical microscope. This stain‐free approach reveals morphological details comparable to traditional H&

Link Bandwidth and Transmission Capability of Single-Mode Multi-Aperture Vertical-Cavity Surface-Emitting Lasers at 100 G/Lane and 200 G/Lane over Multimode Fibers

open access: yesPhotonics
Single-mode (SM) vertical-cavity surface-emitting lasers (VCSELs) have often been demonstrated with an unusually long transmission reach at very high data rates while today’s multimode VCSEL transmission has been limited by the fiber modal bandwidth and ...

Dispersion Supported BB84 Quantum Key Distribution Using Phase Modulated Light

open access: yesIEEE Photonics Journal, 2011
We propose and experimentally demonstrate that, contrary to what was thought up to now, an efficient BB84 operation is feasible using the double phase modulator (PM-PM) configuration in frequency-coded quantum key distribution systems without dispersion ...

Genome‐Wide Association Study Reveals Insect Genetics and Microbial Symbiont Effects on Susceptibility of Diaphorina citri to the Citrus Greening Pathogen, Candidatus Liberibacter Asiaticus

open access: yesAdvanced Science, EarlyView.
This study investigates the genetic and microbial factors influencing the susceptibility of Diaphorina citri to the citrus greening pathogen Candidatus Liberibacter asiaticus (CLas), employing a microbiome Genome Wide Association Study. The research identifies a key gene encoding an MFS‐type transporter contributing to CLas infectivity and abundance in

Chromatic dispersion monitoring in electronic dispersion equalizers using tapped delay lines

open access: yesOptics Express, 2007
We propose a chromatic dispersion monitoring technique by analyzing the tap coefficients in electronic dispersion equalizers using tapped delay lines without needing additional hardware. This technique is robust to varying optical signal-to-noise ratio. The successful chromatic dispersion monitoring is demonstrated by simulation and experiment.

Visualizing and Quantifying Impact with Mechanochromic Sensing Paints Based on Self‐Assembled Polydiacetylene‐Silk Core‐Shell Vesicles

open access: yesAdvanced Science, EarlyView.
Tracking physical impacts is important in many fields. Self‐assembled microparticles made from polydiacetylene and silk fibroin that change color from blue to red when hit can provide an alternative approach to traditional mechanical transducers, quantitatively visualizing impact with responses ranging from <100 to 770 N.

Electrochemical Dye Switching Assisted Spectral Demixing and 3D STORM Imaging

open access: yesAngewandte Chemie, EarlyView.
ABSTRACT Super‐resolution microscopy has advanced cellular imaging by enabling nanoscale resolution, while reliable multicolor strategies remain crucial for resolving multiple targets in complex cellular samples. Here, we demonstrate a two‐color imaging strategy using electrochemically controlled stochastic optical reconstruction microscopy (EC‐STORM),
