Freeform optics, broadly described as optical elements with at least one surface lacking translational or rotational symmetry, have seen increased interest due to recent [...]

This thesis describes the design and verification of a scanning, optical, displacement measurement instrument, which utilizes digital image correlation (DIC) to measure di[...]

Random anti-reflection surface structures (rARSS) are non-periodic, densely packed, sub-wavelength structures, fabricated on an optical surface. Light incident to such a [...]

The tremendous development in digital technology in the last few decades has increased the demand for ultra-precision optical components with enhanced optical performance[...]

Recent advancements in design, manufacturing, and metrology have enabled broader use of freeform components for high-performing optical systems. Freeform optics, which la[...]

Continuous advancement in terahertz technologies have drawn interest in manufacturing and rapid prototyping of optical components suitable for the terahertz spectral rang[...]

The nature and quality of a surface’s topography can play an important role in a part’s performance and expected longevity. The complexity of a surface topography means t[...]

Nonpropagating excitations have been studied in 1-D and in 3-D, but not so much in 2-D. So, this thesis concerns 2-D nonpropagating excitations. In particular, we constru[...]

Vortices in optical beams have been the subject of extensive study since their status as a generic feature of light was established. They have found extensive use in opti[...]

Guided mode resonance filters (GMRF) combine subwavelength gratings and planar slab waveguides to create highly efficient, narrow linewidth spectral filters. Resonances [...]
