Dispersion in a Gas Filled Hollow Core Photonic Crystal Fiber

مجلة بغداد للعلوم, 2014
Hollow core photonic bandgap fibers provide a new geometry for the realization and enhancement of many nonlinear optical effects. Such fibers offer novel guidance and dispersion properties that provide an advantage over conventional fibers for various ...

Photonic Crystal Laser Accelerator Structures [PDF]

, 2003
Photonic crystals have great potential for use as laser-driven accelerator structures. A photonic crystal is a dielectric structure arranged in a periodic geometry.

Low-loss criterion and effective area considerations for photonic crystal fibers [PDF]

, 2003
We study the class of endlessly single-mode all-silica photonic crystal fibers with a triangular air-hole cladding. We consider the sensibility to longitudinal nonuniformities and the consequences and limitations for realizing low-loss large-mode area ...

Hybrid photonic crystal fiber

Optics Express, 2006
We present a hybrid photonic crystal fiber in which a guided mode is confined simultaneously by modified total internal reflection from an array of air holes and antiresonant reflection from a line of high-index inclusions. Experimental results demonstrate that this fiber shares properties of both index-guided and photonic bandgap structures.

A Novel Method for Polarization Squeezing with Photonic Crystal Fibers [PDF]

, 2009
Photonic Crystal Fibers can be tailored to increase the effective Kerr nonlinearity, while producing smaller amounts of excess noise compared to standard silicon fibers.

Sub two-cycle soliton-effect pulse compression at 800 nm in Photonic Crystal Fibers [PDF]

, 2006
The possibility of soliton self-compression of ultrashort laser pulses down to the few-cycle regime in photonic crystal fibers is numerically investigated.

Tapered photonic crystal fibers

Optics Express, 2004
We demonstrate the tapering of a photonic crystal fiber to achieve a microstructure pitch of less than 300 nm. We probe the tapered fiber in the transverse geometry to demonstrate the scaling of the photonic bandgaps associated with the microstructure.

Scanning of Optical Fields Using Near-Field Scanning Optical Microscopy

Communications, 2006
The Near-field scanning optical microscopy is a high-resolution diagnostics for the optical field characterization. In our experiments we focus on the optical field characterization of semiconductor laser diodes based on multiple quantum well structure ...

Axial spectral scans of polarization dependent third harmonic generation in a multimode photonic crystal fiber [PDF]

Journal of the European Optical Society-Rapid Publications, 2007
We demonstrate a nondestructive axial scanning technique for the spectrally resolved analysis of femtosecond nonlinear–optical transformation in photonic crystal fibers.

Symmetrical dual D-shape photonic crystal fibers for surface plasmon resonance sensing.

Optics Express, 2018
Symmetrical dual D-shape photonic crystal fibers (PCFs) for surface plasmon resonance (SPR) sensing are designed and analyzed by the finite element method (FEM).
