ABSTRACT: Periodically poled nanophotonic waveguides in lithium niobate provide a combination of strong nonlinear coupling, low propagation losses, and dispersion engineering unavailable in other platforms, enabling novel phenomena such as efficient femtojoule wavemixing and new routes to generation of coherent multi-octave continua. Various nonlinear interactions, emphasizing ultralow power and few cycle operation, and progress toward the few-photon regime, will be discussed. 

Biography: Martin Fejer is a Professor of Applied Physics at Stanford University, working in the areas of nonlinear optical materials and devices, guided-wave and ultrafast optics, classical- and quantum-optical signal processing, instrument science for LIGO, and materials with low dissipation.
