Earth doped glasses a thesis submitted to the college of graduate studies and research in partial fulfillment of the requirements 121 chalcogenide. In this thesis, electron beam induced deformations are explored as a way of fabricating optical waveguides in ge 02 se 08 chalcogenide glasses because this is an etchless technique that potentially allows writing waveguides whose surface roughness is. Ii this thesis entitled: ge-sb-se chalcogenide glass for near- and mid-infrared nonlinear photonics written by molly rebecca krogstad has been approved for the department of physics.
Stimulated brillouin scattering in a planar chalcogenide glass waveguide shahar levy faculty of engineering phd thesis submitted to the senate of bar-ilan university. A review of some properties of chalcogenide glasses and the current status of their applications is given techniques to characterize the linear and non-linear properties of these glasses are introduced and used to measure the optical constants of chalcogenide glasses in the form of bulk, thin film and fiber. Chalcogenide glasses have several potential uses for new photonic devices for two reasons: i) their infrared (ir) transparency and ii) viscous flow at the glass transition temperature (tg.
Ii abstract the results in this thesis are from our efforts to modify the optical properties of solution-derived chalcogenide glass films by the incorporation of nanomaterials.

Fabrication and characterization of micro-structures created in arsenic trisulfide chalcogenide glasses by multi-photon lithography doctoral thesis thesis.
Chalcogenide glasses are oxygen-free inorganic glasses containing one or more kind of chalcogen elements the amorphous material is a noncrystalline solid, and the glass is amorphous material produced through melt quenching. This thesis entitled theoretical studies of structure and dynamics of chalcogenide glasses by fakharul inam has been approved for the department of department of physics & astronomy. From numerous similarities to the host glass ple lineshape, fatiguing, temperature dependence, and the spectral range over which the effect occurs, the defect states in the glass responsible for the broad band ple are idenitifed as being the same states which give rise to the host glass luminescence in chalcogenide glasses.
