Labs

Graduate student Kenan Gundogdu, left, with Professor Boggess, right, in an ultrafast optics lab. Optical techniques are used to measure semiconductor properties relevant to lasers, detectors, and photovoltaic devices.	From left, graduate students Abdullah Kocbay and Haibin Zheng, postdoctoral researcher Kimberley Hall, and Professor Boggess. Equipment in their labs include ultrafast lasers, a diode-laser testing station, and continuous-wave and time-resolved photoluminescence equipment.	Our Molecular-Beam Epitaxy (MBE) lab has two MBE machines for growing semiconductor nanostructures under highly controlled conditions.
Another view of the MBE lab, with Professor Prineas standing above one of the MBE machines. Semiconductor devices that are grown in this lab include quantum wells and superlattices.	Professor Prineas and a graduate student discussing how samples are transported into the MBE machine.	Another view of the MBE lab. Our research is collaborative; often the devices grown in this lab are characterized by our groups with ultrafast laser labs.
Professor Andersen, right, with graduate student Hai Ming Chen, in their nonlinear optics lab, where they study topics such as the nonlinear optical crossbar switch.	Postdoc Scot Hawkins, left, with graduate student Eric Gansen, in one of Professor Smirl's femtosecond laser labs. They use nonlinear optical techniques to measure quantum mechanical phenomena and coherence in semiconductors.	Graduate students Jason Slattery, left, and Martin Stevens, discussing an ultrafast laser in another of Professor Smirl's labs.
Labs with ultrafast lasers usually have large optical tables loaded with several big lasers and a large number of optical components. Shown here is another of Professor Smirl's labs, which is used for studying the nonlinear optical properties of semiconductors by inserting them into a laser beam.		Professor Wohlgenannt's lab includes this glovebox, which is equipped with e-beam evaporation and thermal evaporation equipment, to deposit materials for his organic semiconductor experiments.
To characterize his organic semiconductor samples, Professor Wohlgennant uses this cw-laser setup.
