摘要：
The light bullet is obtained in tapered graded-index waveguide with parity-time-symmetric potentials. Different kind of parity-time (PT) symmetric potentials admits different shape of light bullet. The result shows the light bullet may be distorted with Rosen Morse PT and sech-type PT-symmetrical potential. Moreover, the size and position of the light bullet can be controlled by changing some key parameters. These results are useful for the potential applications in the tapered graded-index waveguide amplifier with PT symmetric potentials and three-dimensional optical information storage.
