Two-Dimensional Photonic Crystals for Near IR and Visible Optoelectronics Applications
Abstract
The focus of this project is to develop a process for constructing two-dimensional (2D) photonic crystals, which will be amenable to commercialization. Our approach has been to utilize nanochannel glass (NCG), which consists of a 2D hexagonal arrays of cylindrical voids that traverse the entire thickness of the glass. A 2D photonic can be realized with NCG if high index materials with good transmission properties can be introduced into the channels. This is the primary mission and focus of this project. In addition, e-beam lithography techniques are also being utilized to construct prototype two-dimensional photonic crystals that operate in the UV to low IR wavelength region of the light spectrum. The primary discoveries of this work have been theoretical modelling of gas flows in nanoscale structures and models for the formation of novel nanoparticles and nanowires in high aspect ratio structures. The findings of this work suggest that novel chemical sensors could be constructed with channel glass where nanoparticles or nanowires with specific properties have been formed within the channels. In terms of the ultimate goal of the project, 2-D photonic crystals based on nanochannel glass, the final conclusion is that nanochannel glass is not an appropriate foundation with which to construct 2D photonic crystals.
