Current research:
My research focuses on ultrafast photonics and fiber optics, and can be divided into the following main activities:
- Optical signal processing and optical communications: We are investigating all-fiber and planar lightwave circuit devices, as well as linear and nonlinear techniques, for optical signal processing functionality including generating ultrahigh repetition rate pulse trains (> 100 GHz); arbitrary optical waveform generation; all-optical clock recovery; and management in packet-switched networks such as optical buffering, wavelength conversion, and all-optical label swapping. We are also exploring devices and concepts in optical amplification, optical code-division multiple access, and microwave photonics.
- Fiber lasers: Multi-wavelength optical sources are important for numerous applications in optical instrumentation, sensing, and communications. Our objectives are to increase the functionality and capabilities of multi-wavelength sources by developing tunable multi-wavelength fiber lasers operating in continuous-wave and mode-locked regimes. Much of this work is done in conjunction with that in optical signal processing, optical communications, and biophotonics.
- Biophotonics: We are working closely with researchers in optical coherence tomography (OCT) to develop sources (broadband and wavelength-swept) and signal processing algorithms for increasing the capabilities of OCT systems.
