Title: Fabrication of photonic band gap materials

Abstract

A method for forming a periodic dielectric structure exhibiting photonic band gap effects includes forming a slurry of a nano-crystalline ceramic dielectric or semiconductor material and monodisperse polymer microspheres, depositing a film of the slurry on a substrate, drying the film, and calcining the film to remove the polymer microspheres therefrom. The film may be cold-pressed after drying and prior to calcining. The ceramic dielectric or semiconductor material may be titania, and the polymer microspheres may be polystyrene microspheres.

Fabrication of photonic band gap materials using microtransfer molded templates

Patent Leung, Wai; Constant, Kristen; Ho, Kai-Ming; ...

A method of manufacturing photonic band gap structures operable in the optical spectrum has been presented. The method comprises the steps of creating a patterned template for an elastomeric mold, fabricating an elastomeric mold from poly-dimethylsiloxane (PDMS) or other suitable polymer, filling the elastomeric mold with a second polymer such as epoxy or other suitable polymer, stamping the second polymer by making contact with a substrate or multilayer structure, removing the elastomeric mold, infiltrating the multilayer structure with ceramic or metal, and heating the multilayer structure to remove the second polymer to form a photonic band gap structure.

Periodic dielectric structure for production of photonic band gap and method for fabricating the same

Patent Ozbay, Ekmel [Ames, IA]; Tuttle, Gary [Ames, IA]; Michel, Erick [Ames, IA]; ...

A method for fabricating a periodic dielectric structure which exhibits a photonic band gap. Alignment holes are formed in a wafer of dielectric material having a given crystal orientation. A planar layer of elongate rods is then formed in a section of the wafer. The formation of the rods includes the step of selectively removing the dielectric material of the wafer between the rods. The formation of alignment holes and layers of elongate rods and wafers is then repeated to form a plurality of patterned wafers. A stack of patterned wafers is then formed by rotating each successive wafer withmore » « less

Photonic band gap accelerator

Patent Simakov, Evgenya; Shchegolkov, Dmitry

A preferred compact particle accelerator can include a cell arranged along a longitudinal axis along which a particle beam is accelerated. The preferred cell can include a first plate disposed substantially orthogonal to the longitudinal axis and a second plate disposed substantially parallel to the first plate. The preferred cell can also include a first set of rods connecting the first plate to the second plate and disposed at a first radius about the longitudinal axis. Preferably, the first set of rods each defines an elliptical cross section. The preferred cell can also include a second set of rods connectingmore » « less

Highly directional receiver and source antennas using photonic band gap crystals

Patent Biswas, Rana; Tuttle, Gary L.; Ozbay, Ekmel; ...

A directional antenna made with photonic band gap structures has been presented. The directional antenna is formed with two photonic band gap structures oriented back to back and separated from each other by a distance to form a resonant cavity between the photonic band gap structures. An antenna element is placed in the resonant cavity. The resonant frequency of the cavity is tuned by adjusting the distance between the photonic band gap structures. The resonant cavity can be asymmetrical or symmetrical.
