We report on the integration of carbon nanotubes in silicon micro-cavities to develop cost-effective light sources. Strong light coupling from carbon nanotubes was demonstrated into silicon photonics resonators, nanobeam cavities and photonic crystals.
We present a rigorous experimental study of dispersion engineered silicon slot photonic crystal waveguides based in a design that takes into account the best compromise regarding electronic beam lithography, group index, propagation length and losses. Two different interferometric approaches have been implemented to measure the photon delay on several tuned flat band structures in hollow core PhC...
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.
Slot photonic crystal cavities are of great interest for their advantages of small footprint as well as pretty high quality factors and large (Q/V) factors. A series of slot photonic crystal heterostructure cavities with resonant wavelengths in the range 1.3 µm - 1.6 µm has been designed and fabricated with Q of tens of 10000 and (Q/V) reaching 800 000. These works open perspectives for on-chip nonlinear...
Properties of non-freestanding silicon slot photonic crystal cavities for application to sensing are investigated by probing their resonance wavelength tuning as a function of covering material index. Sensitivities of 225 nm/RIU are obtained with Q around 30,000 and cavity mode volumes ∼ V=0.03(λ/n)3
