Dynamic Bragg gratings can be recorded in rare-earth (eg Er, Yb) doped optical fibres by
two counter-propagating mutually coherent laser waves via local saturation of the fibre …

We describe both theoretically and experimentally a polarization independent
interferometric adaptive photodetector based on photorefractive two-wave mixing. The …

We report linear polarization-insensitive detection of optical phase modulation in an
adaptive interferometer based on transient two-wave mixing via dynamic population gratings …

Photo-EMF adaptive photodetectors can be considered as 2D structures of photoinduced pn
junctions optimized for detection of fast displacements of spatially nonuniform light intensity …

A single-detector adaptive configuration for polarization-insensitive homodyne detection of
optical phase modulation is proposed. Experiments were performed at a HeNe laser …

The light polarization fluctuations strongly affect the performance of coherent optical
communication systems due to the fact that to recover the information contained in the phase …

Polarization insensitive detection of optical phase modulation can still be considered as one
of important problems, which is facing, in particular, practical utilization of coherent optical …

Es bien sabido que una iluminación no-uniforme sobre un cristal fotorrefractivo provoca un
cambio espacialmente inhomogeneo de su birrefringencia. Esos cambios llevan a la …
