The goal of this work is to overcome the fundamental size incompatibility between micro-photonics and nano-electronics and to pursue the quest for more efficient nano-scale opto-electronic devices. (more)
The goal of this work is to design effective wavelength-size optical components and to demonstrate them in a planar technology. Such designs and implementations include metallic nano-slit lenses, nano-metallic color filters, nano-patterned transparent electrodes, MDM gradient index lenses.
The goal is to create artificial or "meta"-materials with novel electromagnetic properties by replacing intrinsic electronic states, as they exist in conventional materials, with engineered nano-scale electromagnetic resonances. Examples include metamaterials with large positive refractive index and extreme anisotropy. (more)
In this work I investigate confinement and concentration of mid-infrared light, i.e., radiation that corresponds to the molecular "finger print" range of the electromagnetic spectrum. (more)
The goal is to analyze scaling in FPA pixels and to identify opportunities for wavelength-scale optics that may improve pixel sensitivity. It is an extension of work on solid-state image sensors in the visible range.
The goal is to maintain or even improve pixel sensitivity as image sensor technology scales. This work benefits any type of optical sensing from compact imagers for cell-phones to low-threshold detection in biosensors. It is an application of my doctoral research on the optics of image sensors. It focuses on accurate modeling of light-matter interaction and the consequences of fundamental light properties on solid-state image sensor performance. (more)
