Wavefront assessment and correction of the rat eye for two photon excitation therapies
(University of Waterloo, 2016-08-31)Photodynamic therapy (PDT) is a treatment in which light excites a photosensitive drug to produce oxygen radicals that kills nearby cells. Today, PDT’s is most commonly used application is for the destruction of cancerous ... -
Waveguide Sources of Photon Pairs
(University of Waterloo, 2011-05-04)This thesis describes various methods for producing photon pairs from waveguides. It covers relevant topics such as waveguide coupling and phase matching, along with the relevant measurement techniques used to infer photon ... -
Weak Coherent Pulse Source and Polarization Control for Quantum Key Distribution
(University of Waterloo, 2023-05-30)The Quantum EncrYption and Science Satellite will demonstrate quantum communication from space. One demonstration will be a satellite uplink using a weak coherent pulse source. This thesis will discuss work in minimizing ... -
What can detectors detect?
(University of Waterloo, 2021-01-29)This thesis is focused on using a pair of Unruh-DeWitt detectors, which interact locally with a quantum field, to gain information about properties of the field and the underlying spacetime. First, we consider a massless ... -
Wigner negativity on the sphere
(University of Waterloo, 2023-08-15)The rise of quantum information theory has largely vindicated the long-held belief that Wigner negativity is an indicator of genuine nonclassicality in quantum systems. This thesis explores its manifestation in spin-j ... -
Wormlike Chain Polymers Under External Fields with Applications to Nanotechnology
(University of Waterloo, 2022-08-12)Polymers are long molecular chains formed from smaller molecular units called monomers. Polymers display interesting macroscopic properties, are ubiquitous in everyday materials, and are also important biomolecules among ... -
X-ray Astrophysics: The Spoiler Clusters and XRISM Synchrotron Calibrations
(University of Waterloo, 2019-10-22)Cool core galaxy clusters hosting brightest cluster galaxies (BCGs) in their centres radiate away their energy on timescales of less than 10^9 yr. If cooling wasn't offset by some form of heating, the hot atmosphere would ...
