It is strong Coulomb effects in carbon nanotubes that lead to formation of the so-called "bright" and "dark" (forbidden one-photon optical transition) exciton states, and dramatically decrease the efficiency of one-photon light emission via trapping of the carriers by "dark" states. We demonstrate that the proper use of these "bright" and "dark" exciton states with distinctively different recombination times may turn the situation around: the use of quantum coherence and multiphoton schemes of…

Active Control of Coherent Dynamics in Hybrid Plasmonic MoS2 Monolayers with Dressed Phonons
The near-field interaction due to a strong electromagnetic field induced by resonant localized plasmons can result in a strong coupling of excitonic states or formation of hybrid exciton-plasmon


Direct Observation of Dark Excitons in Individual Carbon Nanotubes: Role of Local Environments
We report the direct observation of the spin-singlet dark excitonic state in individual single-walled carbon nanotubes through low-temperature micro-photoluminescence spectroscopy in magnetic fields.
Generation of single optical plasmons in metallic nanowires coupled to quantum dots
This work demonstrates a cavity-free, broadband approach for engineering photon–emitter interactions via subwavelength confinement of optical fields near metallic nanostructures and shows that efficient coupling is accompanied by more than 2.5-fold enhancement of the quantum dot spontaneous emission, in good agreement with theoretical predictions.
Electromagnetically induced transparency : Optics in coherent media
Coherent preparation by laser light of quantum states of atoms and molecules can lead to quantum interference in the amplitudes of optical transitions. In this way the optical properties of a medium

Two-photon excitation spectroscopy bolsters the exciton picture and demonstrates the dominant role of many-body interactions in the excited-state properties of one-dimensional systems.
Selection rules for one- and two-photon absorption by excitons in carbon nanotubes
Recent optical absorption and emission experiments showed that the lower energy optical transitions in carbon nanotubes are excitonic in nature, as predicted by theory. These experiments were based
Optical stark effect of exciton in semiconducting single-walled carbon nanotubes
An instantaneous blue shift of exciton absorption due to the optical Stark effect was observed in isolated semiconducting single-walled carbon nanotubes (SWNTs) by using a femtosecond (fs) pump-probe
Observation of coherent optical information storage in an atomic medium using halted light pulses
A theoretical model is presented that reveals that the system is self-adjusting to minimize dissipative loss during the ‘read’ and ‘write’ operations, anticipating applications of this phenomenon for quantum information processing.
Radiative lifetime of excitons in carbon nanotubes.
In the limit of rapid interband thermalization, the radiative decay rate is maximized at intermediate temperatures and decreases at low temperature because the lowest-energy excitons are optically forbidden.
Nonlinear Optics at Low Light Levels
The recent observation by Hau and colleagues [1] of ultraslow light propagation (17 mys) motivates the study of nonlinear optical processes under conditions where slow group velocity is a dominant

Observations indicate very strong electron-phonon coupling that allows efficient excitation of electronic states via phonon-assisted processes and leads to ultrafast intraband relaxation due to inelastic electron- phonon scattering.
