This conference talk will sum up our recent contributions related to the integration of semiconductor carbon nanotubes (s-SWNTs) as an active material in silicon photonics. This work is motivated by the possible use of s-SWNTs for light emission, detection, and modulation relying on the same hybrid on-silicon integration platform. We will first describe experimental results carried out to prepare...
We propose in this work an original nanobeam cavity geometry for the hybrid integration of active materials in silicon photonics. The key point of this structure is to use Bragg mirrors exploiting a dielectric dispersion band, to form a field-confining cavity core relying on an air dispersion band. The resulting situation opens the way for a gentle confinement of the electromagnetic field in the low-index...
In this paper, we report our recent results about slotted photonic structures for hybrid on-chip integration in silicon photonics. Explored schemes cover hollow core waveguide optimized micro-ring resonators, slot photonic crystal cavities, and slow light slotted waveguides, all aiming at the enhancement of light-matter interactions. A comparison between several of these approaches is drawn regarding...
A series of slot Si-on-SiO2 photonic crystal heterostructure cavities with resonant wavelengths ranging from 1.28 to $1.6~\mu \text{m}$ is reported. These cavities, presenting $Q/V$ factors typically around 800 000, can be used for the hybrid integration of various active materials within the silicon photonics platform.
