Ultrashort-pulse mode-locked lasers are powerful multi-disciplinary tools. They rely on the formation of stable complex nonlinear optical solitons, and order-of-magnitude performance advances have come from the development of novel solitons including stretched-pulse and chirped pulse solitons. However, while incredibly useful, mode-locked lasers are ultimately limited in their operation wavelength, pulse energy, and repetition rate by the requirement of an efficient gain medium, which restricts system performance and increases the cost of application-specific devices. This talk will discuss new developments in ultrashort-pulse fiber Kerr resonators, a promising alternative to mode-locked lasers. Kerr resonators support femtosecond optical solitons in passive cavities, without the need for a limiting efficient gain medium. This talk will introduce new nonlinear wave phenomena in normal dispersion and dispersion-managed Kerr resonators, including stable chirped pulses that can tolerate very large loss and support high pulse energies and stretched-pulse solitons featuring the shortest pulses observed to date from a fiber Kerr resonator.
