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 …

Summary form only given. Linear detection of the optical phase modulation in a randomly
polarized laser beam is highly important, in particular, for optical fiber sensors and coherent …

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

A simple configuration for the linear homodyne detection of fast phase modulation in the
presence of relatively slow polarisation/phase drift in the signal beam is proposed and …

Conventional coherent optical receivers can only detect a signal efficiently if the signal
energy is contained in a single spatial mode (ie. diffraction limited field-of-view). Detecting …

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

We have demonstrated a simple optical sensing scheme based on a Double Phase
Conjugate Mirror (DPCM) recorded in a Bi 12 TiO 20 waveguide-like sample. In the …

Detection (or demodulation) of the phase modulation is a critical operation in different
photonic applications, in particular, in interferometric fiber sensors, material evaluation via …

The recent development of optical implementations of various data processing procedures
created a demand for a sensitive all optical threshold device [1]. We henceforth present a …
