| Abstract(in English) | Mode-locked lasers which generate precise pulse trains and optical frequency-comb spectra are valuable light sources for use in high-speed communication systems, and in environmental gaseous molecule sensor systems. Such molecule sensor systems’ diagnostic resolutions are strongly affected, too, by the width of frequency-comb’s equally-spaced spectral components. The all-optical semiconductor-gate-based mode-locked laser scheme of this group is supposed to have scientifically significant advantages in terms of the tunability of optical center frequency, the compatibility to conventional integrated planar-wave-guided structures, etc. We’ve recently demonstrated the fact that the increases in the line-widths of both plus and minus first-order comb components (located next to its central component) from the above-mentioned home-made 40-GHz-repetition mode-locked laser are narrower than one MHz. Line-widths of higher-order comb components were, however, not yet characterized. In this work, we carefully characterize the line-widths of both plus and minus second- and third-order comb components from a similar 40-GHz laser, for the first time, to see whether or not the increases in widths of those higher-order comb components are still always narrower than one MHz, which relatively corresponds to 4 ppm with respect to this optical comb’s spacings, 40 GHz. |
