Theoretical Analysis of Spectral Broadening Through Saturable Photoexcited-Carrier Refraction in Graphene-Covered Nanowires

We perform a thorough study of the spectral broadening of short and intense pulses propagating in graphene- covered nanowires departing from a saturable photoexcited-carrier refraction (SPCR) model. In particular, we put forth an analytical expression for the instantaneous frequency of the traversin...
