Statistical And Variational Modeling And Analysis Of Passive Integrated Photonic Devices, Norbert Dinyi Agbodo
Legacy Theses & Dissertations (2009 - 2024)
The success of Si as a platform for photonic devices and the associated availabilityof wafer-scale, ultra-high resolution lithography for Si CMOS has helped lead to the rapid advance of Si-based integrated photonics manufacturing over the past decade. This evolution is nearing the point of integration of Si-based photonics together with Si-CMOS for compact, high speed, high bandwidth, and cost-effective devices. However, due to the sensitive nature of passive and active photonic devices, variations inherent in wafer-based fabrication processes can lead to unacceptable levels of performance variation both within a give die and across a given wafer. Fully understanding the role …
Simulation Of Polycapillary And Multichannel Plate X-Ray Optics, Robert Schmitz
Simulation Of Polycapillary And Multichannel Plate X-Ray Optics, Robert Schmitz
Legacy Theses & Dissertations (2009 - 2024)
Simulation of x-ray optical systems is an important tool for optics design for known applications, and optic development for potential applications. Polycapillary optics are thin glass cylinders containing hundreds of thousands of hollow channels that transmit x rays using total external reflection. These optics have been developed for many applications, from beam filtering to x-ray collimating or focusing. A Monte Carlo based ray-tracing simulation was developed to model a wide range of polycapillary optic geometries. The simulation uses a vector-based approach to model all photons and optical geometries in three dimensions. Simulation verification was performed for a wide range of …
