Optical component |
摘要 |
An optical component is an optical fiber grating element having a grating formed in the core region of an optical fiber, and a cladding region is made of silica glass. An optical material for the core region is ladder-type silicone resin, whose refractive index is set to a desired value by appropriately adjusting the mixing ratio between SiO and a functional group and the mixing ratio of a phenyl group to a methyl group. The optical component has a desired thermal expansion coefficient and desired temperature characteristics as a whole.
