The overall power and far-field pattern of the beam out-coupled from a single-mode planar
proton-exchanged LiNbO 3 waveguide in the α-phase have been studied for in-coupled …

We demonstrate a long-term continuous readout of a two-dimensional image in a
photorefractive holographic memory with a BaTiO3 crystal. A considerable extension of …

We develop a splicing device for photonic crystal fibers (PCFs) based on a double phase
conjugate mirror (DPCM) using a novel photorefractive (PR) Sn 2 P 2 S 6: Sb 1.5% crystal …

Grating erasure in the dark has different temporal characteristics for different crystals. We
present experimental results of four-wave mixing in a BaTiO_3 crystal, which exhibits a large …

We demonstrate long-term readout of a binarized image with a dynamic refreshment
technique by mutually pumped phase conjugate mirrors (MPPCMs). Long-term continuous …

We propose a fundamental interconnection method using a polarization alignment system
for waveguides having different spatial modes. In addition, as an example for the verification …

In this report, we demonstrate a noise reduction recording in a photorefractive memory with
a dynamic refreshing technique by mutually pumped phase conjugate mirrors (MPPCMs) …

A numerical simulation for studying the kinetics of phase-conjugate beams generated by
multigrating four-wave mixing has been developed. It has been applied to investigate the …

We show that the relative phase of the grating components has a large effect on the
temporal behavior of four-wave mixing. When the two main components of the grating are in …

In this paper, we demonstrate long-term readout in a photorefractive memory with a dynamic
refreshment technique by mutual-pumped phase conjugate mirror (MPPCM). The dynamic …
