Silica photonic crystal fiber structure in order to simplify the process of making them [PDF]

Journal of Intelligent Procedures in Electrical Technology, 2014
In this research, a new structure of photonic crystal fibers(PCFs) will be proposed,in which instead of using the aire- holes in the cladding region, the flourine(2%) doped solid silica rods in order to reduce the problems associated with deformities of ...

Multi‐Pathway Upconversion Emission in Symmetry‐Broken Nanocavities: Broadband Multiresonant Enhancement and Anti‐Correlated Interfacial Sensitivity

Advanced Functional Materials, EarlyView.
Symmetry‐broken plasmonic nanoantenna arrays achieve broadband multiresonant enhancement of second harmonic generation (SHG), third harmonic generation (THG), and upconversion photoluminescence (UCPL), under femtosecond laser excitation across the near‐infrared range (1000–1600 nm).

3D Nano‐architected Polymer Shell Enables Reconfigurable Stabilized Blue Phase Soft Crystals

Advanced Functional Materials, EarlyView.
Spherical polymer shells featuring nanostructure of blue phase (BP) disclinations form via in situ photo‐polymerization within BP liquid crystals, providing controlled anchoring for BP nucleation and growth at room temperature and beyond. This architected confinement enhances BP thermal stability over a broad temperature range while enabling dynamic ...

A new slant on photonic crystal fibers

Optics Express, 2004
We present the novel use of microstructured optical fibers not as 'light-pipes', but in a transverse geometry to manipulate the light propagating across the fiber. Fundamental and higher-order bandgaps were observed experimentally in this geometry using a number of techniques.

Photoactivation of NV Centers in Diamond via Continuous Wave Laser Illumination of Shallow As‐Implanted Nitrogen

Advanced Functional Materials, EarlyView.
This study demonstrates an alternative method of creating charge‐stable negatively charged nitrogen vacancy (NV−) centers close to the diamond surface without high‐temperature annealing. By illuminating nitrogen‐implanted regions with a continuous‐wave 405 nm laser, NV− centers are induced, exhibiting electron spin coherence properties suitable for ...
