Birefringence-Managed Normal-Dispersion Fiber Laser Delivering Energy-Tunable Chirp-Free Solitons
Ultrafast Science, 2022 Chirp-free solitons have been mainly achieved with anomalous-dispersion fiber lasers by the balance of dispersive and nonlinear effects, and the single-pulse energy is constrained within a relatively small range.

Birefringence and strain-induced crystallization of stretched cellulose acetate propionate films [PDF]
, 2017 We investigated wavelength dependence of birefringence (Δn) for cellulose acetate propionate (CAP) films stretched at various draw ratios (DRs) and strain rates (SRs), by comparing the result of cellulose triacetate (CTA). CAP exhibited an extraordinary

Birefringence-mediated enhancement of the magneto-optical activity in anisotropic magnetic crystals
, 2021 Optical anisotropy is usually treated as an unfavorable condition for the magneto-optical measurements since it is known to diminish the Faraday rotation concerning the case of the isotropic medium. Here we show that the situation could be quite opposite:

Laser-stimulated birefringence of Ga2O3-La2S2.95Se0.05 glasses for optical recording of information
Results in Physics, 2019 We show an opportunity to change the birefringence of Ga2O3 – La2S2.95Se0.05 glasses doped by Er3+ and La3+ ions at λ = 1150 nm wavelength of cw He-Ne laser under illumination of the femtosecond laser.

Polarization properties of interferometrically interrogated fiber Bragg grating and tandem-interferometer strain sensors [PDF]
, 2006 Lead sensitivity in low-coherence interferometric fiber-optic sensors is a well-known problem. It can lead to a severe degradation in the sensor resolution and accuracy through its effect on the fringe visibility and interferometric phase.

Locally pressed fibre Bragg grating pressure sensor [PDF]
, 2006 A spectral-hole created by locally pressing a fibre Bragg grating exhibited a wavelength-shift within the FBG bandwidth. A sensitivity of 74.3pm/(N/mm) was obtained for pressure applied along the slow axis of a high birefringence ...

Thermal Sensitivity of Birefringence in Polarization-Maintaining Hollow-Core Photonic Bandgap Fibers
Photonics, 2023 Polarization-maintaining (PM) fiber is the core sensitive component of a fiber optic gyroscope (FOG); its birefringence temperature stability is crucial for maintaining accuracy. Here, we systematically investigated the structural thermal deformation and
