Globally Anisotropic High Porosity Silica Aerogels

, 2007
We discuss two methods by which high porosity silica aerogels can be engineered to exhibit global anisotropy. First, anisotropy can be introduced with axial strain.

Modeling-Free Bounds on Nonrenormalizable Isotropic Lorentz and CPT Violation in QED

, 2011
The strongest bounds on some forms of Lorentz and CPT violation come from astrophysical data, and placing such bounds may require understanding and modeling distant sources of radiation.

Spectral-Domain Measurements of Birefringence and Sensing Characteristics of a Side-Hole Microstructured Fiber

Sensors, 2013
We experimentally characterized a birefringent side-hole microstructured fiber in the visible wavelength region. The spectral dependence of the group and phase modal birefringence was measured using the methods of spectral interferometry. The phase modal

Snapshot Multi-Wavelength Birefringence Imaging

Sensors
A snapshot multi-wavelength birefringence imaging measurement method was proposed in this study. The RGB-LEDs at wavelengths 463 nm, 533 nm, and 629 nm were illuminated with circularly polarized light after passing through a circular polarizer.

Strain-induced improvements on linear and nonlinear optical properties of SrB4O7 crystal

AIP Advances, 2012
Although the high nonlinearity, strontium tetraborate crystal SrB4O7 is angular non-phasematched in UV SHG process due to its low birefringence. In this Letter, we revealed that its birefringence can be significantly enhanced by uniaxial strain based on ...

FEM analysis of a highly birefringent modified slotted core circular PCF for endlessly single mode operation across E to L telecom bands

Journal of the European Optical Society-Rapid Publications
This paper describes an exceptionally high birefringent modified slotted core circular photonic crystal fiber (MSCCPCF). At the 1.55 μm telecommunication wavelength, the proposed fiber structure aims to achieve exceptional birefringence performance ...

Experimental investigation on the effect of crystal birefringence on the performance of nanosecond-pulsed diamond Raman laser

Functional Diamond
The impact of crystal birefringence on the performance of diamond Raman lasers has been studied previously at power levels slightly above the threshold.

Resonance enhancement of magnetic Faraday rotation

, 2008
Magnetic Faraday rotation is widely used in optics. In natural transparent materials, this effect is very weak. One way to enhance it is to incorporate the magnetic material into a periodic layered structure displaying a high-Q resonance.

Multipulse soliton attractors facilitated by high-birefringence fibers

Optics Letters
The stability of optical solitons is a crucial factor in various applications. This work reveals a novel, to the best of our knowledge, stable multipulse soliton attractor in fiber lasers. The attractor represents a bound state of multiple solitons, pulling other dynamical states toward itself. By introducing a polarization-maintaining fiber (PMF), the
