title: Group and phase velocity coupling of colliding pulses in a nanostructure.
abstract: It is generally accepted that, in a laser cavity, the group delay--responsible for the round trip time--and the phase delay both have a linear dependence on the cavity length. We show that nanostructures, such as quantum wells, can create a coupling between phase and group velocities, resulting in a periodic dependence of the repetition rate on the laser cavity length.
