My research deals with optical technologies, primarily for communications, signal processing, and networking. Specifically, my research group at USC has explored various issues related to: (a) limitations in fiber and free-space communications, (b) wavelength and spatial multiplexing of different beams of light for capacity enhancement, (c) utilizing nonlinear effects to achieve high-speed optical signal processing, and (d) multiplexing of orthogonal beams that each carry orbital-angular-momentum.
