Abstract
A technique for ultrashort complex pulse generation based on the pulse
shaping of superstructure fiber Bragg grating (SSFBG) is presented. We apply
this technique to illuminate the mutual transformation between Gaussian pulse
and soliton pulse, generations of double optical pulse and complex millimeter
wave (MMW) pulse by phase and amplitude profiling of 1-ps transform-limited
pulse. The designed principle of grating is demonstrated; the corresponding
refractive index distribution, the reflection spectrum and the characteristics
of pulse transmission are also simulated. The results of this study indicate
that this design method is very flexible for complex pulse generations. Finally,
some potential applications for these complex pulses in the areas of ultrafast
photonics, optical measurement, novel devices for optical communication system
and so on are also listed and discussed.
