Bifurcation analysis of a semiconductor laser with filtered optical feedback [PDF]
, 2006 We study the dynamics and bifurcations of a semiconductor laser with delayed filtered optical feedback, where a part of the output of the laser reenters after spectral filtering. This type of coherent optical feedback is more challenging than the case of

Laser-controlled local magnetic field with semiconductor quantum rings [PDF]
, 2005 We analize theoretically the dynamics of N electrons localized in a semiconductor quantum ring under a train of phase-locked infrared laser pulses. The pulse sequence is designed to control the total angular momentum of the electrons.
