Title: Complex photonic crystals for broadband "all-angle" self-collimation
Author: Chuang, Yi-Chen
Date Created: 2010
Subjects--Topical: Optics
Description: Self-collimation is a dispersion property of many photonic crystals (PCs), in which light beam can propagate free of divergence in the PCs. While self-collimation is a desired property for applications related to wave guiding and light collection,...

Title: Effects of Edge Roughness on Optical Scattering from Periodic Microstructures
Author: Bergner, Brent
Date Created: 2009
Subjects--Topical: Optics, Nanotechnology
Description: Planar photonic crystals and other microstructured surfaces have important applications in a number of emerging technologies. However, these structures can be difficult to fabricate in a consistent manner. Rapid, precise measurements of critical p...

Title: Electromagnetic Wave Phenomena In Periodic Metastructures
Author: Schenk, John
Date Created: 2010
Subjects--Topical: Electrical engineering, Optics, System theory
Description: There is an active effort toward the development of negative index metamaterials for application in high-resolution imaging. In particular, engineering an artificial material exhibiting an index of exactly -1, may permit sub-wavelength imaging. Th...

Title: Intracellular Subsurface Imaging Using a Hybrid Shear-Force Feedback/ Scanning Quantitative Phase Microscopy Technique
Author: Edward, Kert
Date Created: 2009
Subjects--Topical: Optics
Description: Quantitative phase microscopy (QPM) allows for the imaging of translucent or transparent biological specimens without the need for exogenous contrast agents. This technique is usually applied towards the investigation of simple cells such as red b...

Title: MECHANISTIC STUDY OF SELF-ASSEMBLED TUNGSTEN NANOGRATINGS ON SOLIDS INDUCED BY FEMTOSECOND LASER BEAM
Author: Tang, Mingzhen
Date Created: 2010
Subjects--Topical: Optics
Description: This dissertation describes a mechanistic study on the spontaneous formation of tungsten nanograting induced by a 400 nm femtosecond laser beam on solids observed in laser induced chemical vapor deposition configuration. The formed tungsten nanogr...

Title: PHASE STRUCTURED WAVEFIELDS WITH PHASE SINGULARITIES AND BISPECTRAL PROPERTIES
Author: Scipioni, Marco
Date Created: 2010
Subjects--Topical: Optics
Description: The work presented in this dissertation can be subdivided into two parts. The first part illustrates the novel use of a 37 actuator segmented deformable mirror for the creation of optical vortex beams ranging in topological charge from 1 to 10. Th...
