Abstract
A method of encapsulating an optical component, the component comprising at least partially uncoated organic material, the method comprising: placing molten metal around the optical component, and solidifying the metal. The invention includes encapsulating a segment or element of an optical component, such as, for example, an optical junction or a surface. An encapsulated optical component and optical components having sealed or encapsulated elements are also provided.
Claims7
An encapsulated optical component comprising:
- an optical component encased in low-melting metal, the optical component prior to encapsulation comprising at least partially uncoated organic material, in which the low-melting metal is selected from the group consisting of the following alloys and mixtures thereof:
- 58/58, 95/95, 93/87, 137/96, 138/138, 115/95, 133/96, 167/120, 180/96, 118/118, 130/121, and 93/93.
An encapsulated optical planar coupler comprising:
- an optical planar coupler encased in metal, the optical planar coupler prior to encapsulation comprising at least partially uncoated organic material, further comprising:
- protective means covering at least one junction between an optical fiber connected to the planar coupler and a light pathway of the planar coupler.
