Zero-birefringence pressure-sensitive adhesives

open access: yesAIP Advances, 2012
We have developed zero-birefringence pressure-sensitive adhesives (PSAs) that exhibit almost no birefringence at any orientation of polymer chains. To evaluate the birefringence of PSAs quantitatively, we report a novel birefringence-measurement method ...

Optical rheology of porcine sclera by birefringence imaging. [PDF]

open access: yesPLoS ONE, 2012
To investigate a relationship between birefringence and elasticity of porcine sclera ex vivo using polarization-sensitive optical coherence tomography (PS-OCT).Elastic parameters and birefringence of 19 porcine eyes were measured.

Acoustic Birefringence Changes in the Base Metal and Heat Affected Zone of ASTM 1020 Steel under Plastic Deformation and Fatigue [PDF]

open access: yesE3S Web of Conferences, 2023
This paper deals with metallographic studies and ultrasonic investigations of acoustic birefringence in the base metal and heat affected zone of welded specimens of ASTM 1020 steel under uniaxial tension and low-cycle fatigue. We examined microstructural

5D data storage by ultrafast laser nanostructuring in glass [PDF]

open access: yes, 2013
The high-density five dimensional data storage with ultrafast laser writing is demonstrated. The text file is recorded by polarization controlled self-assembled form birefringence and retrieved in glass opening the era of unlimited lifetime data ...

Modification of Orientation Birefringence of Cellulose Ester by Addition of Poly(Lactic Acid) [PDF]

open access: yes, 2010
Effect of the addition of poly(lactic acid) (PLA) to cellulose acetate propionate (CAP) on the optical anisotropy is studied considering the morphology and molecular orientation.

Cosmic birefringence from the Axiverse [PDF]

open access: yes, 2023
We revisit the evidence for CMB birefringence in the context of a rich Axiverse. Using probability density functions (PDFs) for various axion parameters, such as the mass and axion decay constant, we construct the PDF for the cosmic birefringence angle ...

Visible to mid-infrared giant in-plane optical anisotropy in ternary van der Waals crystals

open access: yesNature Communications, 2023
Birefringence is at the heart of photonic applications. Layered van der Waals materials inherently support considerable out-of-plane birefringence.

Twisted Hi-Bi fiber DFB lasers with controllable output polarization [PDF]

open access: yes, 2012
We demonstrate that single polarization, hi-bi fiber DFB lasers are in general characterized by elliptical state of polarization, due to the in-built fiber birefringence axis rotation.

A Linear Birefringence Measurement Method for an Optical Fiber Current Sensor

open access: yesSensors, 2017
In this work, a linear birefringence measurement method is proposed for an optical fiber current sensor (OFCS). First, the optical configuration of the measurement system is presented.

Interactions of bound multiple solitons in strongly birefringent fibers [PDF]

open access: yes, 1995
The interaction of bound multiple solitons generated by two orthogonally polarized high-amplitude pulses is experimentally studied in a strongly birefringent fiber.
