Fourier transform infrared spectroscopy of 6.1-Angstrom semiconductor quantum wells
The 6.1-Angstrom (A) family of III-V semiconductors---InAs, GaSb, and AlSb and their alloys and heterostructures---has unique properties that may find application in next generation multi-functional semiconductor devices. ...
Plasmonic nanostructures on silicon
The intersection of silicon technology with the rapidly growing field of nanoplasmonics, provides a fertile ground for development of synergistic technologies. The optical and electrical properties of silicon are well ...
Space-time cross correlations of diffuse broadband terahertz waves
We describe observations of the amplitude and phase of an electric field diffusing through a three-dimensional random medium by using Terahertz Time-Domain Spectroscopy. These measurements are spatially resolved with a ...
Magneto-optical Kerr effect and magnetic circular dichroism in ferromagnetic indium-manganese-arsenic/gallium-antimony heterostructures
This thesis describes a Magneto-Optical Kerr Effect (MOKE) and Magnetic Circular Dichroism (MCD) study of ferromagnetism in III-V magnetic semiconductor heterostructures. This work was initiated due to the much recent ...
Development of compact DSP based mid-infrared quantum cascade laser spectrometers
This thesis describes the development of digital signal processor (DSP) and quantum cascade laser (QCL) technology for compact, standalone, integrated, trace gas sensors capable of gas sensing at part-per-billion (ppb) ...
Terahertz imaging with compressive sensing
Most existing terahertz imaging systems are generally limited by slow image acquisition due to mechanical raster scanning. Other systems using focal plane detector arrays can acquire images in real time, but are either too ...
