Abstract
Disclosed herein is a coated optical fiber comprising: a siliceous optical fiber including a core inside a cladding; and a cured coating comprising: a thermally cured polyorganosilsesquioxane; and an oxide powder dispersed in said cured polyorganosilsesquioxane, wherein said oxide powder has a refractive index from about 1.2 to about 2.7 and includes a plurality of particles having a particle size less than about 100 nanometers, said cured coating having adhesion to said siliceous optical fiber and further having transparency to ultraviolet radiation. Also disclosed herein is a fiber optic device comprising the optical fiber.
Claims8
A coated optical fiber comprising:
- a siliceous optical fiber including a core inside a cladding;
- and
- a cured coating comprising:
- a thermally cured polyorganosilsesquioxane;
- and
- an oxide powder dispersed in said cured polyorganosilsesquioxane, wherein said oxide powder has a refractive index from about 1.2 to about 2.7 and includes a plurality of particles having a particle size less than about 100 nanometers, said cured coating having adhesion to said siliceous optical fiber and further having transparency to ultraviolet radiation.
A fiber optic device comprising:
- an optical fiber having sensitivity to radiation;
- a cured coating transparent to said radiation, said cured coating comprising:
- a cured polyorganosilsesquioxane;
- and
- an oxide powder dispersed in said cured polyorganosilsesquioxane to provide said cured coating having adhesion to said optical fiber;
- and
- a radiation induced variation of refractive index in said optical fiber produced during passage of said radiation through said cured coating to provide said fiber optic device.
