Spatial mode multiplexing is used to transmit several communication channels on a single
multimode optical fiber. Each channel is encoded by an orthogonal pattern produced by a …

We demonstrate a self-adapting homodyne detection system working at a wavelength of
1.55 μm. The system uses a photorefractive CdTe: V crystal as the element that combines …

In this paper, we present a new design of the interferometer, intended for high-precision
measurements of electric fields. We combined both arms of the interferometer in one …

We report an experimental method that combines nonlinear-crystal-based transient
detection imaging (TDI) with interferometric complex-field retrieval. The system allows …

This paper presents the results of a theoretical analysis of the contribution of the inverse
flexoelectric and photoelastic effects to the photorefractive response that accompanies …

We present a strain sensor in which a multimode fiber is used as a sensitive element. High
sensitivity to dynamic strains is achieved by means of vectorial wave mixing in a …

Application of dynamic population gratings recorded in rare-earth doped optical fibers for
adaptive detection of laser induced ultrasonic signals is considered. The most important …

We demonstrate experimentally the operation of an adaptive two-wave mixing interferometer
with no field applied to a photorefractive crystal in which the quadrature condition is …

Предложена и исследована схема для мультиплексирования ортогональных
динамических голограмм, формируемых в фоторефрактивном кристалле, практически …

The characteristics of a holographic interferometer, which is based on the interaction of
counterpropagating light waves on reflective holograms in cubic photorefractive sillenite …
