Waveguide writing using a train of femtosecond laser pulses at 850 nm, in the transparent
spectral region of bulk As40S60 glasses is reported. Waveguides were written by translating …

This paper reports on the fabrication process of As-S-(Se)-based chalcogenide glass optical
waveguides using three techniques: photolithography, laser beam writing, and ion …

First-and second-order Bragg reflectors at telecommunication wavelength (1.5 m) were
fabricated in single-mode monolayer (As2S3) and multilayer (As-S-Se/As-S) chalcogenide …

Ultrafast pulsed laser deposition was used to successfully deposit atomically smooth 5-μm-
thick As_2S_3 films. The as-deposited films were photosensitive at wavelengths close to the …

Sub-band-gap irradiation of a series of bulk Ge-As-Se glass samples with a tunable laser
source shows that photostructural processes in chalcogenide glasses are strongly …

It is shown that the magnitude of photostructural changes in chalcogenide glass is a function
of the connectivity and fragility of the glass network. Glasses with a floppy network undergo …

A detailed calorimetric study of photostructural changes in glasses of the Ge-Se system is
presented. The photomodified structure corresponds to a distinct entropy state intermediate …

The ability to locally photoinduce optical index change and volume expansion has
encouraged extensive study of the chalcogenide glass family. Fabrication of microlenses …

Bragg gratings are used in several photonic devices to reflect, and thus to isolate, specific
wavelengths of light. Gratings can be photoinduced in chalcogenide glasses by illumination …

Stimulated Brillouin scattering (SBS) amplification is obtained in directly written As_2S_3
channel waveguides. Centimeter-long waveguides were written using a Ti: sapphire …
