A spectroscopic investigation of novel doped glasses for active infrared devices
… glasses have been studied for their potential as infrared amplifier materials. Optical amplifiers which operate outside of the C-band are likely to form part of future optical telecoms systems. This work is focused on transition metal and rare earth-doped materials which could provide gain in the …

Measurement of 'one over f noise' in infrared detection using a novel technique
… in Mercury Cadmium Telluride (HgCdTe) infrared devices. It is therefore imperative to be able to measure and account for its contribution to the total device noise. In this thesis, the 1/f noise of a HgCdTe device is measured and studied using two measurement techniques. The first …

Synthesis and Applications of Large-Area Monolayer Graphene
… of metal-graphene interfaces for electronic devices. In parallel, we explored diverse applications of graphene, including its role as a transparent, flexible electrode in organic solar cells, along with several collaborative efforts demonstrating its use as a sensor for cardiac microtissues, …

Spectral Signature Modification By Application Of Infrared Frequency-selective Surfaces
… signature of a surface, particularly in the infrared (IR) region of the electromagnetic spectrum. To alter the surface signature in the IR, two methods are investigated: thin film application and antenna array application. The former approach is a common and straightforward incorporation of …
