Optical Design for an Open Access Trapped Ion Quantum Processor
(University of Waterloo, 2021-08-31)The future of quantum information is scaling to a ever larger number of qubits. Doing so will require advances in the approach for all aspects of current experimental systems. The QuantumION project is a large step in this ... -
Optical Fiber Sensors for Temperature and Strain Measurement
(University of Waterloo, 2010-12-09)Optical fiber sensors have already been developed from the experimental stage to practical applications in the past 20 years. There is no doubt that this technology can bring a wealth of applications, ranging from sensors ... -
Optical pulse compression of first anti-Stokes order in the multi-frequency Raman generation with the presence of red shifted shoulder
(University of Waterloo, 2018-09-11)Multi-frequency Raman generation (MRG) is a nonlinear technique to generate intense trains of single-femtosecond pulses. The broad spectrum of different Raman orders which is spread from near-infrared (near-IR) to UV can ... -
Optical Pulse Shaping For Chirped Pulse Interferometry And Bio-Imaging
(University of Waterloo, 2011-09-02)Biomedical imaging requires high resolution to see the fine features of a sample and fast acquisition to observe live cells that move. Optical coherence tomography (OCT) is a powerful technique which uses optical ... -
Optical Quantum Communication & Cryptography with Temporarily Trusted Parties
(University of Waterloo, 2019-09-19)The work in this thesis can be divided into three parts. The first two parts deal with optical quantum communication protocols and the third part deals with quantum cryptography. The first part of the thesis is a step ... -
Optical Resonators Integrated into a Hollow Core Photonic Crystal Fiber for Enhanced Light-Matter Interactions
(University of Waterloo, 2019-08-29)The focus of this thesis is to investigate and fabricate a platform that can facilitate the enhancement of light-matter interactions. By tightly confining the photons and atoms to the same region of space, the probability ... -
Optics, Loss and Gravity
(University of Waterloo, 2021-01-13)We look at some ideas that can be found from making connections among optics, non-Hermitian dynamics and gravity. Using nonlinear optics, we demonstrate how loss can be used to make brighter sources of thermal light. Also, ... -

(University of Waterloo, 2022-01-13)The WarmTone is a fully automatic, modern-day vinyl record press manufactured by Viryl Technologies. The WarmTone has a wide array of sensors, parameters and settings that can be accessed via it's ADAPT Interface and the ... -
Optimization of an All Normal Dispersion Fiber Laser and a Gain Managed Nonlinear Amplifier
(University of Waterloo, 2023-07-17)Ultrafast laser systems are used in a wide variety of modern laser research. The combination of an all-normal dispersion fiber laser and a gain-managed nonlinear fiber amplifier makes for inexpensive and easy to build ... -
Optimization of MBE growth of a high-quality 2-Dimensional Electron Gas in InAs/AlGaSb material system for pursuing a top-down approach towards realization of topological qubits.
(University of Waterloo, 2020-09-04)Two-dimensional electron gas (2DEG) in InAs quantum wells grown on nearly lattice-matched GaSb substrates is an ideal platform towards the realization of topological quantum computing with Majorana fermions, due to its low ... -
Optimization of the Optical Infrastructure and Trapping Potential for a Quantum Processor Based on Trapped Barium Ions
(University of Waterloo, 2024-02-02)Trapped ion quantum computers represent a cutting-edge quantum computing platform, keeping the highest reported state preparation and measurement fidelity of 99.97%. Recently, barium ion has emerged as the research ... -
Optimizing Small-scale Redshift Space Distortion Measurements in eBOSS for Cosmological Inference
(University of Waterloo, 2023-09-21)Modern cosmological datasets have grown substantially in size and the precision of their measurements. While the improvement has had a beneficial impact on our understanding of the cosmological model, it requires equal ... -
Ordering and Reverse Ordering Mechanisms of Triblock Copolymers in the Presence of Solvent
(MDPI, 2009-02-27)Self-consistent field theory is used to study the self-assembly of a triblock copolymer melt. Two different external factors (temperature and solvent) are shown to affect the self-assembly. Either one or two-step self-assembly ... -
Ordering mechanisms in triblock copolymers
(American Physical Society, 2004)The ordering mechanisms for an ABC triblock copolymer system are studied using self-consistent field theory. We find a two-phase mechanism, similar to what has been suggested experimentally two-step mecha- nism. Analysis ... -
Orientation and Transitions of Lyotropic Lamellar Phase under Shear
