Tailoring carbon nanotubes optical properties through chirality-wise silicon ring resonators

Abstract Semiconducting single walled carbon nanotubes (s-SWNT) have an immense potential for the development of active optoelectronic functionalities in ultra-compact hybrid photonic circuits. Specifically, s-SWNT have been identified as a very promising solution to implement light sources in the s...
