“…One, from the viewpoint of nanoscale physics and their applications in the next generation nano-optoelectronic devices [1,2] ranging from photon generation [3,4], and from nanoscale integrated photonic detectors [5]. Combined with plasmonics, these one-dimensional systems offer a potential technological solution to interface near-field optics and nano-electronics in the pursuit to establish a controlled optical exchange.…”

In this work, we demonstrate propagating surface plasmon polariton (SPP) coupled photoluminescence (PL) excitation of single-walled carbon nanotube (SWNT). SPPs were launched at a few micrometers from individually marked SWNT, and plasmon-coupled PL was recorded to determine the efficiency of this remote in-plane addressing scheme. The efficiency depends upon the following factors: (i) longitudinal and transverse distances between the SPP launching site and the location of the SWNT and (ii) orientation of the SWNT with respect to the plasmon propagation wave vector (k SPP ). Our experiment explores the possible integration of carbon nanotubes as a plasmon sensor in plasmonic and nanophotonic devices. [8,10,11], and large optical gain [12] create a strong motivation to explore the integration of SWNT optical properties in a plasmonic platform.In this Letter, we report on remote in-plane photoluminescence (PL) excitation of individual SWNT by propagating SPPs in metal thin film strip waveguides. Our experiment provides critical information on the coupling properties between a propagating surface plasmon mode and electronic resonances of an individual SWNT.High pressure carbon monoxide (HiPCO) synthesized SWNTs were dispersed in a 1% wt. sodium dodecyl sulfate solution by sonication and were subsequently processed by centrifugation [8]. The nanotubes used in our experiment range in diameter between 0.7-1.2 nm. Nanotubes were randomly deposited on top of plasmonic waveguides by spin coating. The strip waveguides were fabricated by standard electron-beam lithography and lift-off processes on indium tin oxide (ITO)-coated cover glass slips. The structure consists of Au strips of varying length (∼10-30 μm), with a width of 5 μm and a thickness of 35 nm.

Semiconducting carbon nanotubes (s-SWNT) are efficiently extracted from a raw nanotube powder using an ultracentrifugation method with a conjugated polymer as extracting agent. This method leads to obtention of almost metallic-free s-SWNT samples, displaying strong photoluminescence properties. An integration scheme to couple s-SWNT optical properties with silicon waveguide using processes compatible with silicon technology is proposed, and we demonstrated the emission of s-SWNT throught the silicon waveguide at a wavelength of 1.3 µm. This integration scheme is used to couple s-SWNT with silicon microring resonators. Sharp emission peaks originating from light coupled and resonating inside the microring are observed, with quality factors around 3000.

“…A complete study of the coupling between carbon nanotubes and silicon waveguides was performed. 48 The integration scheme considered is based on the insertion of an interacting zone in an input/output silicon waveguide. It is constituted of a sub-micron waveguide embedded in a carbon nanotubes composite, as schematically presented in Fig.…”

Carbon nanotubes are more and more considered for future use in microelectronics. On the other hand, the use of optics to overcome the limitation of metallic interconnects start to be considered as a viable solution. Carbon nanotubes are promising candidate to bridge the gap between optics and microelectronics, thanks to their ability to emit, modulate and detect light in the wavelength range of silicon transparency. In this proceeding, we will first underline the use of carbon nanotube for photonics. We will then show that thin film doped with semiconducting carbon nanotubes displays strong optical gain at a wavelength of 1.3 µm. Finally, we will report the integration of carbon nanotube thin layer with silicon waveguide, and present the successfull coupling of their absorption and emission properties. This leds to the demonstration of temperature independent emission from carbon nanotubes in silicon at a wavelength of 1.3 µm.
