Research Projects

  • Femtosecond pulses

    Femtosecond pulses

    Femtosecond pulses being transmitted through water has recently shown that these pulses sustain much less loss than longer pulses, particularly at long distances. Femtosecond pulses are used to create terahertz radiation, whose transmission through a variety of media is being investigated.

  • Electronic instrumentation

    Electronic instrumentation

    Electronic instrumentation research includes development of a new type of non-contact optical sensor of vibration and other motion. New designs for free space optical communications are under study, both for transmission through the atmosphere and through water. Active and passive waveguides are needed for optical signal processing, telecommunications, optical data storage, and other applications. Fiber optics devices such as tunable filters and fiber lasers are being designed and built.

  • Nonlinear optical studies

    Nonlinear optical studies

    Nonlinear optical studies investigate second- and third-order nonlinear effects in optical glass fibers, thin films, and semiconductor structures. A novel project is ultrafast pulse shaping of wavelets for high bandwidth fiber-optic free-space systems. Nonlinear devices are being investigated for high-speed image processing and for time-to-wavelength conversion for communication systems.

  • Semiconductor devices and opto-electronics

    Semiconductor devices and opto-electronics

    Semiconductor devices and opto-electronics research has several components. Studies of carrier transport through quantum wells, using picosecond optical pulses, demonstrate the importance of hole motion. Improved materials for trapping photo-induced carriers are being explored, and improved non-linear optical semiconductor devices are being designed and tested.
