| Research Abstract |
In this project, first of all, a practical ultra wideband light source covering whole visible region was developed using photonic crystal fibers and ultrashort pulse fiber laser system. Next, the all optical control of visible pulse was demonstrated for the first time using novel phenomenon of pulse trapping. Then, an ultrafast wavelength tunable pulse source was developed and quasi-wideband light source generation was demonstrated. The ultrahigh resolution cross-sectional imaging was demonstrated using the developed light source.
