Abstract: Silicon photonic devices need to be complemented with other materials for the realization of optically active devices. The unique emission properties of single-walled carbon nanotubes are especially promising for efficient light emitters realization in the telecommunication wavelength ranges and for their integration in silicon photonic devices. However one of the problem of carbon nanotubes is their low quantum efficiency. One of the approach to address this problem is to couple the carbon nanotube emission with micro-resonators in order to the enhance their radiative emission. Here we report on the fabrication and optical characterization of a silicon micro-slot-ring resonator coupled with selected single walled semiconducting carbon nanotubes for high photoluminescence emission in the O band telecommunication wavelength. Hyperspectral photoluminescence maps show spectra with sharp resonances superimposed to the nanotube emission bands which demonstrate the coupling of the nanotubes with the evanescent tails in air of the electric field localized in the photonic modes of the micro-resonator. The enhancement of the photoluminescence is achieved over three different CNTs chirality for more than 30 sharp resonances in a single microring resonator. This work paves the way for the development of integrated light sources based on carbon nanotubes in silicon photonic devices. [ABSTRACT FROM AUTHOR]
