We observe the strong photorefractive (PR)-like effect in silica micro-fibers, which is different
from the previously reported nonlinear behaviors in optical fiber devices. The micro-fiber is …

We have used the photorefractive two-beam-coupling technique to measure the nonlinear
coefficient (n_2/A_eff) of several telecommunication fibers and investigated the dependence …

We report a theoretical and experimental study of the refractive index variation in a heavily
doped erbium silica fiber within the spectral range 1500–1580 nm under the pumping at the …

Over the past few years microstructured fibers have shown potential for many practical
applications and permitted significant progress in various domains such as nonlinear optics …

It is well known that germanium-doped silica and a number of other fiber materials exhibit
photorefractivity; that is, their refractive index changes in the process of exposure to …

Optical nonlinearities limit the maximum power that can be transmitted through an optical
fiber transmission system. 1 The intensity dependent refractive index n 2 leads to a variety of …

A 980-nm pump-induced nonlinear refractive-index (n_2) change in erbium-doped (20-m)
and ytterbium-doped (20-m) fibers has been measured at 1064? nm by time-delayed …

Nonlinear optical properties of microfiber resonators are investigated. First, a miniature
optical resonator standing in air is realized out of a silica microfiber, and measurements of …

This work proposes a new route to overcome the limits of the thermal poling technique for
the creation of second order nonlinearity in conventional silica optical fibers. We prove that it …
