Near-field imaging of single walled carbon nanotubes emitting in the telecom wavelength range

International audienceHybrid systems based on carbon nanotubes emitting in the telecom wavelength range and Si-photonic platforms are promising candidates for developing integrated photonic circuits. Here, we consider semiconducting single walled carbon nanotubes (s-SWNTs) emitting around 1300 nm or 1550 nm wavelength. The nanotubes are deposited on quartz substrate for mapping their photoluminescence in hyperspectral near-field microscopy. This method allows for a sub-wavelength resolution in detecting the spatial distribution of the emission of single s-SWNTs at room temperature. Optical signature delocalized over several micrometers is observed, thus denoting the high quality of the produced carbon nanotubes on a wide range of tube diameters. Noteworthy, the presence of both nanotube bundles and distinct s-SWNT chiralities is uncovered

Carbon Nanotubes Integration on Silicon

International audienceOptical interconnects are expected to overcome the copper link bottlenecks. Amongthe different developed technologies, silicon photonics becomes one of the preferred solutions. Indeed,due to its compatibility with the CMOS platform, silicon photonics is considered as aviable solution for the development of the future generation photonic interconnects. However,the on-chip integration of all photonic and optoelectronic building blocks (sources, modulatorsand detectors. . . ) on the silicon platform is very complex and is not cost-effective due to thevarious materials used: Ge for detection, Si for waveguiding and modulators and III-V for lasing.We propose here to use carbon nanotubes (CNTs) integrated into silicon photonics for the developmentof all optoelectronic devices. Indeed, CNTs are nanomaterials of particular interest inphotonics thanks to their fundamental optical properties including near-IR luminescence, Starkeffect, Kerr effect and absorption. In consequence, CNTs have the ability to emit, modulateand detect light in the wavelength range of the silicon transparency. Furthermore, they are alsoconsidered as an electronic compatible material thanks to the recent advances in nanoelectronicsbased on CNTs.Here, we report on the study of the light emission coupling from CNTs into optical resonatorsimplemented on the silicon-on-insulator (SOI) platform including ring resonators, nano-beamcavities, micro-disks. . . . A theoretical and experimental analysis of the light interaction of CNTswith micro-ring resonators based on slot waveguides and slot photonic crystal heterostructurecavities will be presented
