Abstract
In some implementations, an optical component includes an optical medium, the optical medium having a surface, wherein the surface includes one or more hydroxyl group terminations; and a surface layer chemically bonded to the optical medium, such that the surface layer has a thickness of less than 10 nanometers and is a hydrophobic surface, the surface layer including at least one of: a hexamethyldisilazane material, a polysiloxane material, a polydimethylsiloxane material, a fluoro-polymer material, an organosilicon material, or an organofluorine material.
Claims12
An optical component, comprising:
- an optical medium, the optical medium comprising a fiber having a surface,
- wherein the optical medium is disposed in a non-sealed environment,
- wherein a first portion of the fiber has a first diameter,
- wherein a second portion of the fiber has a second diameter that is different than the first diameter, and
- wherein the surface includes one or more hydroxyl group terminations before application of a surface layer;
- and
- the surface layer chemically bonded to the surface of the fiber, such that the surface layer has a thickness of less than 10 nanometers and is a hydrophobic surface,
- the surface layer including at least one of:
- a hexamethyldisilazane material,
- a polysiloxane material,
- a polydimethylsiloxane material,
- a fluoro-polymer material,
- an organosilicon material, or
- an organofluorine material.
An optical system, comprising:
- an optical medium, the optical medium comprising a fiber having a surface layer chemically bonded to an exterior of the fiber, such that the surface layer is a hydrophobic surface,
- wherein the optical medium is disposed in a non-sealed environment,
- wherein a first portion of the fiber has a first diameter,
- wherein a second portion of the fiber has a second diameter that is different than the first diameter, and
- wherein the surface layer is a hexamethyldisilazane (HMDS) layer bonded to the exterior;
- and
- a coating material,
- wherein the coating material covers a portion of the optical medium not covered by the surface layer.
