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 partial region. On sintering the soot melts to fill up the empty spaces and thereby create a composite layer.
