MF4.1 - THE INFLUENCE OF ANGULAR MOMENTUM ON FIBER NONLINEAR OPTICS
Abstract
Abstract
Fibers stably supporting an ensemble or orbital angular momentum modes yield new selection rules on account of spin-orbit interactions and the large modal density of stable states afforded by this system. This talk will review recent nonlinear optics experiments with fibers supporting singular light beams.MF4.2 - MULTIMODE INTERFERENCE TUNABLE FILTER IN CHALCOGENIDE FIBER
Abstract
Abstract
We demonstrate a tunable multimode interference filter, assembled with chalcogenide fibers. This filter has an insertion loss of 1.46 dB, a FWHM bandwidth of 26 nm, and a wavelength tunability of 84 nm from 1926 nm to 2010 nm.
MF4.3 - TRACKING THE DISPERSIVE PROPAGATION OF A FAST WAVEFORM USING A TEMPORAL PHASE MODULATOR
Abstract
Abstract
We propose and numerically demonstrate a novel method to evaluate the temporal evolution of a fast optical waveform as it propagates through a group-velocity dispersive medium by tracking the frequency spectrum of the waveform at the output of a quadratic temporal phase modulator (time lens).

Abstract
Abstract
We present the results for two tantalum borides (TaB and TaB2) as potential saturable absorbers for Q-switched lasers. When incorporated to a ring ytterbium laser operating at 1080 nm, they produced pulse widths as short as 345 ns.
