Welcome to the Optical Communications Laboratory at the University of Southern
California. Led by Professor Alan E. Willner, this research lab is a member of the
Communications Sciences Institute within the
Department of Electrical
Engineering - Systems at USC.
Fondly called "OC Lab," our research group focuses on a wide range
of topics in optical fiber communications. Our research interests include combating
fiber-induced signal impairments arising from nonlinearities, chromatic
dispersion and polarization mode dispersion. We also pursue research in
the areas of all-optical networking functions, novel applications of RF subcarrier & OFDM
transmissions, advanced modulation formats, optical signal
processing, slow light and micoring resonators. The group presents papers each year at the Optical Fiber Communications conference (OFC), European
Conference on Optical Communi-cations (ECOC), and Conference on Lasers and
Electro-Optics (CLEO). In addition, we publish articles in journals, such as IEEE Photonics
Technology Letters (PTL), IEEE/OSA Journal of Lightwave Technology (JLT), Optics Letters, Optics Express
and so forth.

The Optical Communications
Laboratory at USC features over 2,500 square feet of space, with
high-performance capabilities for high-speed experiments on
integrated-photonic devices. Our capabilities enable us to carry out systems
experiments using the interconnect devices for WDM
links and >160-Gbit/s data rate. Additionally our measurement equipment
enables us to characterize the integrity of signals due to various devices
(lasers, filters, modulators, waveguides, receivers), including measurements
of bit error rate, operation bandwidth, crosstalk, chirp, polarization
dependent loss, birefringence, and tuning speed.
