Chalcogenide glasses are defined as a new category of non-crystalline solids on the basis
of their characteristic covalent bonds and unique properties, such as broad infrared …

Optical microresonators confine light to a particular microscale trajectory, are exquisitely
sensitive to their microenvironment, and offer convenient readout of their optical properties …

Glass microsphere resonators that support optical resonances known as whispering‐gallery
modes are unique tools for studying and exploiting optical effects under extremely well …

In this review paper some recent advances on optical fiber sensors are reported. In
particular, fiber Bragg grating (FBG), long period gratings (LPGs), evanescent field and …

High-index-contrast compact microdisk resonators in thermally evaporated As_2S_3 and
Ge_17Sb_12S_71 chalcogenide glass films are designed and fabricated using standard UV …

Chalcogenide glasses (ChGs) are technologically superior materials, and their properties
underpin the demands of whispering gallery mode–based integrated photonic devices. The …

Amorphous thin films of Ge_2Sb_2Te_5, sputter-deposited on a ZnS-SiO_2 dielectric layer,
are investigated for the purpose of understanding the structural phase-transitions that occur …

Laser action has been demonstrated in chalcogenide glass microsphere. A sub millimeter
neodymium-doped gallium lanthanum sulphide glass sphere was pumped at 808 nm with a …

We report the first observation of a nonlinear process in a chalcogenide microresonator.
