Spring 2014
This thesis presents the realization and characterization of passive and active photonic and nanoplasmonic waveguides for applications in all-optical circuitry. The key results focus on generating visible light in nanoscale silicon waveguides through nonlinear interactions and demonstrating...

Narreto, Mary Alvean Balmadres
In this thesis, the ultrafast photoluminescence and photoconductivity dynamics of different types of semiconductors are investigated. Using time-resolved photoluminescence and time-resolved terahertz spectroscopy techniques, the origin of the light emission and the nature of carrier transport are...

Fall 2015
Ultrafast carrier dynamics in silicon nanocrystals (Si NCs) is explored using time-integrated photoluminescence, time-resolved photoluminescence and pump-probe transient absorption spectroscopies. The role of surface oxygen in the optical emission dynamics of dodecyl functionalized Si NCs is...

Ultrafast terahertz (THz) spectroscopy is presently the most powerful tool available to materials scientists for directly probing ultrafast conductivity dynamics. Its low center frequency and phase-resolved measurement, which yields sub-picosecond temporal resolution, make it ideally suited for...

Fall 2013
Terahertz spectroscopy is a powerful non-contact technique to study the optical and electric properties of materials at sub-picosecond time scales. In this study, ultrafast time-resolved terahertz spectroscopy was performed on both silicon-on-sapphire (SOS) and iron pyrite (FeS2) nano-crystalline...
