Effect of light Polarization on the absorption index of alkali metal vapor in optical pumping phenomenon
Recently atomic magnetometers are one of the best tools in biomagnetic measurement such as magnetic field of brain and heart. In this paper, the technology of optically pumped atomic magnetometer based on circularly polarized light absorption pumping is described. We have been investigated a new method for measuring polarization effect in an alkali vapor based on polarized light transmission. I...
متن کاملOptical Measurements: Polarization and Coherence of Light Fields
The Chapter is devoted to consideration of metrological aspects of intrinsically interconnected characteristics of light fields, such as intensity, polarization and coherence. Conceptually, all these quantities are derived from the Wolf’s coherency matrix [1]. However, new insight on interconnection of them is provided by the novel singular-optical approach [2, 3] predicting existence of import...
متن کاملPolarization-sensitive optical frequency domain imaging based on unpolarized light.
Polarization-sensitive optical coherence tomography (PS-OCT) is an augmented form of OCT, providing 3D images of both tissue structure and polarization properties. We developed a new method of polarization-sensitive optical frequency domain imaging (PS-OFDI), which is based on a wavelength-swept source. In this method the sample was illuminated with unpolarized light, which was composed of two ...
متن کاملObservation of light-by-light polarization control and stabilization in optical fibre for telecommunication applications.
In many photonics applications, especially in optical fibre based systems, the state of polarization of light remains so far an elusive uncontrolled variable, which can dramatically affect the performances of that systems and which one would like to control as finely as possible. Here, we experimentally demonstrate light-by-light polarization control via a nonlinear effect occurring in single m...
متن کاملPhotonic Crystal-Based Polarization Converter for Optical Communication Applications
A photonic crystal-based TE to TM polarization converter for integrated optical communication is proposed in this paper. The photonic crystal consists of air circular-holes in slab waveguide. The radius of holes are determined to be 291nm having lattice constant of 640nm using the gap map and band diagram. The polarization converter is composed of an InGaAsP triangular-shaped waveguide on SiO2 ...
