Designing for Degradation: Transient Devices Enabled by (Nano)Cellulose

Advanced Materials, EarlyView.
Recent progress in transient devices enabled by (nano)cellulosic materials is reviewed. Transiency mechanisms, advantages of nanocelluloses, and a suite of applications are discussed. A circular thinking approach coupled with life cycle assessment is applied to critically revisit the potential, advantages, and challenges of nanocellulose‐enabled ...

Hollow-Core Photonic Crystal Fibers for Surface-Enhanced Raman Scattering Probes

International Journal of Optics, 2011
Photonic crystal fiber (PCF) sensors based on surface-enhanced Raman scattering (SERS) have become increasingly attractive in chemical and biological detections due to the molecular specificity, high sensitivity, and flexibility. In this paper, we review

Photonic Crystal Fiber in Photonic Crystal Fiber for Residual Dispersion Compensation Over ${\rm E} + {\rm S} + {\rm C} + {\rm L} + {\rm U}$ Wavelength Bands

IEEE Photonics Journal, 2013
A photonic crystal fiber in photonic crystal fiber (PCF-in-PCF) architecture is numerically investigated for residual dispersion compensation in optical transmission link. The optimized structure shows a flattened and high average dispersion of -457.4 ps/

Leakage properties of photonic crystal fibers

Optics Express, 2002
An analysis of the con.nement losses in photonic crystal fibers due to the finite numbers of air holes is performed by means of the finite element method. The high flexibility of the numerical method allows us to consider fibers with regular lattices, like the triangular and the honeycomb ones, and circular holes, but also fibers with more complicated ...

Molecular Control of the Donor/Acceptor Interface Suppresses Charge Recombination Enabling High‐Efficiency Single‐Component Organic Solar Cells

Advanced Materials, EarlyView.
The outstanding double‐cable‐based single‐component material, DCPY2, exhibits a suppressed charge recombination process alongside efficient charge generation. This results in a high fill factor and short‐circuit current, yielding an efficiency to 13.85%.

Endlessly mono-radial annular core photonic crystal fiber for the broadband transmission and supercontinuum generation of vortex beams

Scientific Reports, 2019
We demonstrate a new guiding regime termed endlessly mono-radial, in the proposed annular core photonic crystal fiber (AC-PCF), whereby only modes of the fundamental radial order are supported by the fiber at all input wavelengths.

Avoided crossings in photonic crystal fibers

Optics Express, 2011
The impact of avoided crossings (also known as anti-crossings) in single and double-clad large mode area Photonic Crystal Fibers (PCFs) suitable for high-power laser systems is evaluated numerically. It is pointed out that an inappropriate choice of pump core diameter, bending radius and/or index depression may lead to avoided crossings that manifest ...
