Research Abstract

The effect of higher order fiber-optical soliton is often used for ultrashort pulse compression. Indeed, 20 femto-second (fs) pulse generation or shorter is possible through the method, which corresponds to only four cycles of 1500 nm electromagnetic wave. In order to clarify the ultimate performance and its limiting factors in the lower boundary of the time domain, we have utilized the phenomena of higher order fiber-optical soliton compression. Furthermore, we discussed on the framework for optimization of the spectral shapes thus generated for optical communication light source of multiple carriers. We have reached the conclusion, which includes some newly achieved knowledge, that the fourth order dispersion is an important feature for the ultimate characteristics of ultrashort fiber-optic soliton pulses since it leads to the limiting factor in the time domain and affects the high bandwidth super-continuum generation. The followings are the results obtained in the present research.
( … More 1)The shortest fiber optic soliton pulse ever reported has been successfully derived. Its time period is 15.6 fs. We believe that the new temporal area in the fiber-optic ultrafast photonics has been established.
(2)We pointed out that the ultimate pulse width of fiber-optical soliton is restricted by the fourth order dispersion through the anomalous dispersion bandwidth. This has been confirmed experimentally by means of systematic investigation on temporal widths of generated pulsed under a variety of conditions. Indeed, this is the first clear evidence that the fourth order dispersion effect of an optical fiber appears in a realistic and clear manner.
(3)On the other hand, we found out experimentally that the fourth order dispersion effect can give rise to efficient parametric gain generation of broadband. Also, the theoretical explanation for the phenomena has been established.
(4)On the basis of the results of (3), we demonstrated a few new schemes for broadband optical spectrum generation methods. Less
