Abstract
A hollow core fiber is provided. The hollow core fiber includes at least one cleaved fiber end-face and a dielectric coating. The dielectric coating is formed by a passivation layer of dielectric that is applied to the at least one cleaved fiber end-face such that a portion of an interior surface that defines a hollow core of the hollow core fiber adjacent to the at least one cleaved fiber end-face is coated with the dielectric coating.
Claims13
A hollow core fiber comprising:
- at least one cleaved fiber end-face;
- and
- a dielectric coating formed by a passivation layer of dielectric applied to the at least one cleaved fiber end-face such that a portion of an overall length of an interior surface that defines a hollow core of the hollow core fiber adjacent to the at least one cleaved fiber end-face is coated with the dielectric coating to create a passivation protected end that prevents contamination.
A hollow core fiber:
- at least one cleaved fiber end-face;
- and
- a dielectric coating formed with a passivation layer of dielectric applied to the at least one cleaved fiber end-face with a chemical vapor deposition system such that a portion of an overall length of an interior surface that defines a hollow core of the hollow core fiber adjacent the at least one cleaved fiber end-face is coated with the dielectric coating to create a passivation protected end that prevents contamination, wherein a depth of the portion of the interior surface that defines the hollow core of the hollow core fiber that is adjacent to the at least one cleaved fiber end-face with the dielectric coating is a depth in which air can diffuse within the hollow core.
