Ultrafast phase-resolved self-acceleration and frequency-chirp in silicon chip-scale slow-light solitons

摘要

We demonstrate the first soliton self-accelerations and frequency-shifts induced by Drude free-carrier dispersion in 1.5-mm silicon photonic crystals. Picojoule soliton center-of-mass advancement of 2-ps (about one FWHM) and wavelength blue-shift of 0.8-nm are observed via XFROG.
