In Jan 2021, Henry Francis published a research paper entitled “Optical Frequency Comb Generation via Cascaded Intensity and Phase Photonic Crystal Modulators” in IEEE Journal of selected topics in quantum electronics（Vol.27, Issue.2, March-April 2021）
In this paper, we propose OFC generation based on all-optical modulation of photonic crystal nano-structures. The proposed system offers OFC generation with tunable comb line spacing using devices with high density integration capabilities.
Congratulations!
