PLANAR WAVEGUIDES |
摘要 |
Planar waveguides are produced by using radiation to write path regions into a photosensitive layer: Originally, the photosensitive layer had the same refractive index as the confining regions, e.g. it consists of silica doped with oxides of Ge and B Composite path regions are produced by depositing a glass soot onto a partia l region. On sintering the soot melts to fill up the empty spaces and thereby create a composite layer.
