Birefringent microstructures fabricated by two-photon polymerization containing an azopolymer
(Optical Society of America - OSAWashington, 2013-01)
Birefringent materials have many applications in optical devices. An approach to obtain optically induced birefringence is to employ a guesthost strategy, using a polymer matrix containing an azodye. However, such method ...
Electric Birefringence of Aqueous Solutions of a Rigid Polyelectrolyte. Polarization Mechanisms and Anomalous Birefringence Signals
(American Chemical Society, 2016-08)
We present an electric birefringence study of aqueous solutions of an intrinsically rigid polyelectrolyte, xanthan, and of mixed solutions with an oppositely charged surfactant, DTAB. The stationary electric birefringence ...
Temperature dependence of photoinduced birefringence in polystyrene doped with Disperse Red-1
(Wiley-Blackwell, 2002-11-25)
A theoretical model on the basis of the free-volume concept is presented explaining the temperature dependence of photoinduced birefringence in polystyrene films that contain Disperse Red-1. Birefringence increases with ...

Photonic filters using optical retarders based on birefringent optical media.
(2018-07-19)
Photonic filters can be used for filtering the espectrum of wide-band optical sourcers such a ligth emmitting diodes (LED) or multimode laser diodes (MMLD). In this work the use of birefringent optical media such a ...
Temperature dependence of photoinduced birefringence in mixed Langmuir-Blodgett (LB) films of azobenzene-containing polymers
(Elsevier B.V., 2002-06-01)
The temperature dependence of photoinduced birefringence was investigated for mixed Langmuir-Blodgett (LB) films from the homopolymer poly[4'-[[2-(methacryloyloxy)ethyl]ethyl-amino]-2-chloro-4-nitroazobenzene] (HPDR13) and ...
