TL;DR: Experimental results on the propagation of an interference pattern of two He-Ne laser beams of unequal amplitudes through a photorefractive Bi(12)TiO(20) crystal in the presence of drift nonlinearity are presented.

TL;DR: In this paper, the spectral transmission response of a long-period holey fiber grating mechanically induced in two different twisted holey fibers was investigated and it was shown that each resonance wavelength of the grating splits when the fiber is twisted prior pressure application, and the new upper and lower resonance wavelengths show an opposite symmetrical shift that increases proportionally with the induced twist ratio.

TL;DR: An automatic method to obtain cells detection and cells migration tracking in order to analyze cells behaviors under different conditions using phase-contrast video microscopy method is proposed.

TL;DR: In this article, a temperature sensor based on multimode interference was designed, fabricated and tested, which is very simple and inexpensive since we only need to splice a section of multimode fiber between two single mode fibers.

TL;DR: By direct interferometric measurement in Bi 12 TiO 20 under external DC electric field, the steady-state photorefractive lens produced by the laser beam with the initial circular cross-section is essentially anisotropic: its focusing strength along the direction of the applied electric field is remarkably higher as mentioned in this paper.
