Molten alloys under high pressure were used to obtain fibers with long internal electrodes
that are solid at room temperature. An integrated Mach–Zehnder interferometer was …

Stoichiometric silicon nitride (Si3N4) is one of the most mature integrated photonic platforms
for linear and nonlinear optical applications on-chip. However, because it is a …

1.1 Overview Silica glass is technologically very important, especially in
telecommunications, because of its excellent properties such as strength and the ability to …

Broadband tunability of the second-harmonic wavelength is achieved in periodically poled
silica fibers. A wavelength tuning range of almost 45 nm of the fundamental wave is …

A two-dimensional (2D) numerical model is implemented to describe the movement of ions
under thermal poling for the specific case of optical fibers. Three types of cations are …

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 …

We measure the values of individual χ^(2) tensor components in a birefringent periodically
poled silica fiber through spectrally separated type I and type II second-harmonic …

A special kind of microstructured optical fiber is proposed and fabricated in which, in
addition to the holey region (solid core and silica-air cladding), two large holes exist for …

We study the temporal evolution of both the second-order nonlinear coefficient and of the
nonlinear thickness in thermally poled silica-glass slides by using a high-resolution all …

Active mode-locking of a fiber laser with an all-fiber electrooptic modulator is demonstrated.
A 1.4-V driving signal was used, creating subnanosecond single pulses at the fundamental …
