Negative Kerr nonlinearity of graphene as seen via chirped-pulse-pumped self-phase modulation
Nathalie Vermeulen, David Castello-Lurbe, JinLuo Cheng +6
We experimentally demonstrate a negative Kerr nonlinearity for quasi-undoped graphene. Hereto, we introduce the method of chirped-pulse-pumped self-phase modulation and apply it to…
