OSA Understanding aging in chalcogenide glass thin films
Chalcogenide glass (ChG) thin films have a wide range of applications in planar photonics that rely on the stability of their optical properties. However most methods do not provide quantitative optical property data at sufficiently high resolution. We have employed a resonant cavity refractometry technique capable of detecting refractive index changes down to 10 #x22126 refractive index

Chalcogenidesan overview ScienceDirect Topics
A particular interest in silicon chalcogenide glasses containing Li 2 S Na 2 S or Ag 2 S lies in their ionic conductivity. 29 Si NMR has been used to monitor changes in the glass structures containing these additions and indicates that Ag shows the greatest tendency to form edge–sharing units followed by Li then Na (Pradel et al. 1995).

WOA1Chalcogenide glass lens production method
The present invention provides a production method for obtaining readily a chalcogenide glass lens having excellent transmittance in the infrared region. This production method has a step of extrusion forming a softened chalcogenide glass material (1) into a lens shape preferably fitting the chalcogenide glass material (1) inside a syringe (2) equipped with an extrusion nozzle (5) at the

OSA Ultrafast all-optical chalcogenide glass photonic
Chalcogenide glass films deposited by thermal evaporation sputtering and wet chemical spin deposition all require a post-process anneal in order to bring about bulk glass like properties. Pulsed laser deposition of chalcogenide glass films has been proposed as a means of circumventing this step as the ablated materials has moderately high

OSA Low loss Ge-As-Se chalcogenide glass fiber
Chalcogenide glass fibers have attractive properties (e.g. wide transparent window high optical non-linearity) and numerous potential applications in the mid-infrared (MIR) region. Low optical loss is desired and important in the development of these fibers. Ge-As-Se glass has a large glass-forming range to provide versatility of choice from continuously varying physical properties.
