| 英文摘要 | PCT No. PCT/DE94/00635 Sec. 371 Date Dec. 4, 1995 Sec. 102(e) Date Dec. 4, 1995 PCT Filed Jun. 8, 1994 PCT Pub. No. WO94/29757 PCT Pub. Date Dec. 22, 1994The invention relates to an optical component consisting of transparent thin layers of differing thickness and refractive indices. Such optical components are used, for example, as interference filters and mirrors. Optical components made of layers with gradually changing refractive indices are also known as waveguides of anti-reflective coatings. The invention achieves the aim of using, instead of layers of ordinary materials, another material by means of a component in which the layers consist of porous silicon. The special advantages of porous silicon as a coating material arises not only from the ease and economy of manufacture, but also in the facility for obtaining gradual refractive index transitions. It is therefore very easily possible to make waveguides on a silicon chip. |
