Abstract
A configuration enabling passive modelocking in an optical fiber device is disclosed, utilizing the non-linear Kerr effect. Various configurations are disclosed, using both standard and polarization maintaining fiber, and a bulk optics implementation. One embodiment comprises a figure of eight arrangement formed by two cross-coupled fiber loops, one of the loops being a Sagnac mirror. A further embodiment exploits the non-linearity of polarization in polarization maintaining fibers.
