Abstract
The specification describes a method for selectively depositing carbon nanotubes on the end face of an optical fiber. The end face of the optical fiber is exposed to a dispersion of carbon nanotubes while light is propagated through the optical fiber. Carbon nanotubes deposit selectively on the light emitting core of the optical fiber.
Claims9
A method for selectively depositing carbon nanotubes onto an end face of an optical fiber comprising the steps of:
- immersing the end face of the optical fiber with a liquid wherein said liquid comprises, at least, a dispersion of carbon nanotubes;
- propagating light through the optical fiber so as to illuminate a first region of the end face of the optical fiber, wherein said illumination causes said carbon nanotubes to deposit onto a substantial portion of the illuminated first region.
A method for selectively depositing carbon nanotubes onto an end face of a light emitting element, comprising the steps of:
- immersing the end face of the light emitting element with a liquid wherein said liquid comprises, at least, a dispersion of carbon nanotubes;
- propagating light through the light emitting element so as to illuminate only a first region of the end face of the light emitting element, wherein said illumination causes said carbon nanotubes to deposit onto a substantial portion of the illuminated first region.
