Slowing down velocity and controlling time delay of optical pulses in fiber have many potential applications in optical communication systems, and a number of theoretical and experimental studies have been done. In this paper, the transmission spectrum an
The Eu2 /Tb3 /Sm3 co-doped oxyfluoride glass ceramics containing Ba2LaF7 nanocrystals are prepared in the reducing atmosphere. The X-ray diffraction results show that Eu2 , Tb3 and Sm3 ions are enriched into the precipitated Ba2LaF7 nanophase after the
We present the numerical results of both head-on and non-head-on collisions between two stable dissipative optical bullets (DOBs) in a three-dimensional complex Ginzburg-Landau equation with cubic-quintic nonlinearity. The system parameters chosen are in
