Og. Okhotnikov et Jr. Salcedo, PASSIVELY MODE-LOCKED FIBER LASER-BASED ON POLARIZATION ROTATION IN AMULTIPLE-QUANTUM-WELL WAVE-GUIDE, Optics letters, 20(1), 1995, pp. 67-69
We give experimental evidence for a new type of mode-locking mechanism
for Er-doped fiber lasers based on polarization evolution in an intra
cavity multiple-quantum-well waveguide. Experiments indicate that anis
otropic properties of waveguides can continuously start the mode-locki
ng process.
