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 and detectors in the silicon photonics platform. Here we present our most recent results on the hybrid integration of s-SWNT with silicon resonators, including micro-rings, micro-disks and photonic crystal cavities. We show chirality-wise resonant enhancement of s-SWNT emission, allowing on-chip selection of (8,6) or (8,7) SWNT chiralities present in a high-purity polymer-sorted solution. We also demonstrate that, opposite to the common knowledge, the longitudinal component in transverse-magnetic optical modes can efficiently interact with drop-casted s-SWNTs arranged along the chip surface. The proposed hybrid integration approach unlocks new tools to optimize light-SWNT interaction in silicon photonic circuits and open a new route towards single-chirality selection in hybrid Si-SWNT devices, even if the SWNT solution contains various chiralities. Hence, these results stand as an important step towards the implementation of s-SWNT-based devices for the silicon photonics platform.
