Index-antiguided (IAG) waveguide is promising for high-power application due to simple step-index structure and the property to introduce higher waveguide loss for higher[...]

A unifying theme of this thesis is the implementation and characterization of point probes for surface metrology. The implementations include two optical non-contact prof[...]

A novel multi-frequency (polydyne) optical interferometry method is introduced and a prototype developed to evaluate its performance in a Michelson displacement interfero[...]

The objective of this research is to explore a mathematical model developed by Wilkinson and Pratt for the external cavity fiber-based Fabry-Perot interferometer (EFPI) a[...]
