This paper presents a Lagrangian laboratory study of the passive tracer transport in and around lateral, open-channel (square) cavity. Using 3D-particle tracking velocimetry (PTV), trajectories neutrally buoyant seeding particles are measured analyzed to investigate processes governing particle exchanges between cavity adjacent main stream for selected subcritical flow condition. The tracked cl...

We perform an analytical study of the external cavity modes of a semiconductor laser subject to conventional optical feedback as modeled by the well-known Lang-Kobayashi equations. Specifically, the bifurcation set is derived in the threedimensional parameter space of feedback phase, feedback strength and pump current of the laser. Different open regions in this space correspond to different nu...
