Ultrafast pulse-shape-driven dynamics in optical waveguides

Fiber optics provide a convenient way to deliver light to remote locations otherwise optically inaccessible. Arguably, optical fibers represent the most effective means of delivering optical radiation through nearly arbitrary paths. The delivery of ultrashort pulses through fibers is a topic of interest for a variety of applications yet constitutes a challenge due to the physical interaction between the intense light fields and the bulk constituents of the fiber. The nonlinear optical effects that take place induce a variety of distortion on the pulses which alter the features of the optical field at the output of the fiber. The ability to control these nonlinearities and use them as means to passively control the pulse characteristics at the output end of the fiber would be of extreme practical use. Phase sensitive pulse measurement techniques are a crucial element needed for the characterization of the pulses and to control their shape so that fibers and femtosecond phenomena may coexist effectively and advantageously.
