We study theoretically the perpendicular electrostatic field effect (the quantum confined Stark effect) for excitons and interband surface plasmons in small-diameter (∼1nm) semiconducting carbon nanotubes. We show that the quantum confined Stark effect allows one to control the exciton-plasmon coupling strength in individual nanotubes. This effect may be used for nanotube based tunable optoelectronic device applications in areas such as nanophotonics, nanoplasmonics, and cavity quantum electrodynamics.
