Optical component including nanoparticle heat sink
An optical fiber assembly includes at least one optical component configured to deliver light from a first end to a second end opposite the first end. The at least one optical component includes at least one localized heat-sensitive area that emits increased temperatures with respect to remaining areas of the at least one optical fiber in response to light traveling through the localized heat-sensitive area. The optical fiber assembly further includes a nanoparticle heat sink that contacts the optical component and that completely surrounds the localized heat-sensitive area such that the nanoparticle heat sink dissipates heat from the at least one optical component.
