University of Twente
Dawson Bonneville received his Bachelor and PhD from McMaster University, Canada in Engineering Physics, specializing in integrated photonics with a variety of materials for amplifiers and sensors and now is a Postdoc in the Integrated Optical Systems group at University of Twente in the Netherlands. Here he is continuing his research on integrated photonics with a focus on sputter deposited aluminium oxide for UV photonics as well as erbium doped alumina for amplifiers and lasers.
Presentations
UV Photonics and Rare-earth Doped Amplifiers with Sputter-deposited Aluminium Oxide Waveguides
This talk will highlight the recent work on the reactively sputtered passive and active aluminium oxide waveguide platform. Al2O3 waveguides demonstrate low losses in the UV and telecommunication wavelengths, and including various rare earth elements during sputtering allows for the monolithic integration of doped waveguides with active capability enabling devices such as amplifiers and lasers. The fabrication, recent highlights, and current work will be discussed, with focus on low-loss UV development and erbium doped amplifiers for operation at 1550 nm.
