• Novel tools for ultrafast spectroscopy 

    Jarvis, Thomas William (2011-12)
    Exciton dynamics in semiconductor nanostructures are dominated by the effects of many-body physics. The application of coherent spectroscopic tools, such as two-dimensional Fourier transform spectroscopy (2dFTS), to the ...
  • Tunable bound-states in continuum by optical frequency 

    Boretz, Yingyue Li (2013-12)
    We demonstrate the existence of tunable bound-states in continuum (BIC) in a 1-dimensional quantum wire with two impurities by an intense monochromatic radiation field. We found that there is a new type of BIC due to the ...
  • Widely tunable terahertz semiconductor laser sources 

    Jiang, Aiting (2015-12)
    Terahertz Quantum Cascade Lasers (THz QCLs) and Terahertz Difference Frequency Generation Quantum Cascade Laser sources (DFG-QCLs) are two types of semiconductor THz radiation sources that are compact and amenable to ...
