| 摘要 |
<p>The present invention is directed to optical systems, e.g. wave guide systems, comprising at least (a) a first material which is a poly(perfluorocyclobutane), and in direct contact to this material (b) a second material which is a polycyanate resin. Preferably, both the first and the second materials are in the form of a thin layer, the layers directly adhered to each other. If the system is a wave guide system, either the waveguide can be made from the first material and at least one of the buffer layer and the cladding layer can be made from the second material, or vice versa. In a preferred embodiment, the second material is a polymer of an organic polyfunctional cyanate which is at least partly or fully fluorinated, or a copolymer comprising at least one of the said organic polyfunctional cyanates, optionally in mixture with other components.</p> |
