Fascination with light has been one of the major themes in the history of physics. In modern research, optics—the study of electromagnetic radiation and its interaction with matter—continues to be a driving force in science and technology. Researchers at SFU employ light for probing and manipulating diverse forms of matter, including semiconductors, metals, superconductors, DNA, and spin-polarized noble gases for NMR.
Present areas of study include:
• Time-domain terahertz spectroscopy of metals and superconductors (Dodge).
• Optical properties of semiconductors from the far infrared to the visible
(Thewalt).
• Femtosecond and picosecond transient spectroscopy (Dodge, Thewalt).
• Nonlinear optical spectroscopy (Dodge).
• Near-field optical microscopy of biological molecules (Bechhoefer).
• Spin-polarization of noble gases for MRI imaging of porous media (Hayden).
• Photoluminescence spectroscopy of excitons in semiconductors (Thewalt).
• Fourier-transform infrared spectroscopy of semiconductors and superconductors
(Clayman, Thewalt).
• Raman spectroscopy of superconductors (Irwin).
