Room-temperature single-photon generation from solitary dopants of carbon nanotubes

Abstract: On-demand single-photon sources capable of operating at room temperature and the telecom wavelength range of 1,300-1,500 nm hold the key to the realization of novel technologies that span from sub-diffraction imaging to quantum key distribution and photonic quantum information processing. Here, we show that incorporation of undoped (6,5) single-walled carbon nanotubes into a SiO2 matrix can lead to the creation of solitary oxygen dopant states capable of fluctuation-free, room-temperature single-photon emissio… Show more

“…For a review of nanomanipulation-facilitated hybrid nanophotonic structures see [181]. Single-photon emission from intrinsic [182] and doped [183] carbon nanotubes (CNTs) has led to efforts in constructing scalable hybrid photonic circuits. Large-scale deterministic placement of CNTs by dielectrophoresis [184] was recently utilized to construct integrated QPICs featuring on-chip generation, guiding and detection of single photons [185].…”

“…For comparison, we also simulate the properties of the SPP waveguide modes when the silver nanowire is placed on a glass substrate (refractive index n glass = 1.5), and the simulation results are displayed in Figure b. Herein, the wavelength is set to be λ = 1310 nm . It should be stressed that the choice of this particular wavelength is arbitrary, and that the structural geometry can always be tuned to match the desired resonant wavelength in the nanoslit.…”

“…The thickness of the silver and air in the simulation model are 300 and 2700 nm, respectively. The emission wavelength of the quantum emitter is set to be λ = 1310 nm . The quantum emitter oriented along the z ‐axis is chosen because its total emission rate is several dozen times that of the quantum emitters oriented along the x ‐ or y ‐axis .…”

“…26 Their utility has already been demonstrated as high conductivity channels for field effect transistors, 27-28 photoabsorbers in solar cells, [29][30][31][32] and NIR light emitters. [33][34] For all of these applications, semiconducting carbon nanotubes are required, which must be purified from their metallic counterparts. There are several methods for doing so, each of which creates different types of films.…”
