S2: Optical Materials & Devices
Session 1: Active Optical Materials
Light emitting and optically-active materials and devices are enabling elements within a wide variety of modern technologies. This symposium will address the processing and properties of optical materials as well as design, fabrication, and performance of active optical devices. Of particular focus will be inorganic, organic, and hybrid glasses and crystals in bulk, think film, or fiber form that exhibit light-emissive, nonlinear, electro-optic, magneto-optic, and related active optical phenomenon.
Session 2: Photosensitivity and Laser Modification of Glasses
Organizers: Mario Affatigato, Coe College | Denise Krol, University of California-Davis |
Takayuki Komatsu, Nagaoka University of Technology
This session will be open to presentations in the area of laser interaction with glasses. In particular, it welcomes papers on the topics of femtosecond interactions; thermal mechanisms for structural change; laser induced crystallization; laser damage from electronic mechanisms; laser induced nanostructures; photosensitivity; and general papers on laser induced property changes in glasses. Experimental results, computer models, and other explorations of light-induced Program Chairs: changes are appropriate.
Glasses are important materials for optical fibers and on-chip photonic devices given their excellent optical transparency and capacity for low-loss fiber and planar processing. Novel oxide and non-oxide glass compositions and fabrication technology development have further enabled emerging applications such as light emission, nonlinear optical signal processing, evanescent wave spectroscopy, and sensing. This session will cover material synthesis and processing as well as device fabrication and applications of innovative device architectures including nanostructured optical fibers, photonic crystals, and optical micro-cavities.
Session 4: Optical Absorption
Organizer: Mark Davis, Schott North America, Inc.
All aspects relating to absorption and/or redirection of energy in glass and related materials will be the subject of this symposium, including:
– absorption, including intrinsic and extrinsic sources and their temperature dependencies
– energy trapping
– resonance behavior
– characterization techniques
Theoretical and experimental approaches are welcome.
Optical interference filters based on multilayer coatings allow achieving various optical functions and therefore find a wide range of applications from telecommunication to biomedical. These coatings can be made from different materials (e.g., metals, dielectric, and polymers) and deposited on various substrates. Despite the maturity of the technology, numerous challenges exist in order to achieve optimal performances. A non-exhaustive list of those one includes the control and the characterization of the optical properties, the spatial control of the layer thickness or refractive index for fabricating gratings, photonic band-gap structures or waveguides, the study of the electrical and mechanical properties of coatings, and the functionalization of coatings for optical sensors. This session intends to cover all aspects of optical coatings on materials, components, and devices.
Session 6: Optical Ceramics and Glass Ceramics
Organizer: Robert J. Pavlacka, Army Research Lab
Ceramics with transparency in the visible or IR spectrum are useful for applications such as solid state lasers, transparent armor, high temperature windows, missile domes, and scintillators. This session will focus on processing, characterization, and performance of transparent ceramic materials and devices. Some topics of interest include novel green forming methods, sintering and advanced densification methods, grain boundary characterization, optical and mechanical behavior, and device performance.
