| 摘要 |
The present invention is in the field of optical components, more particularly, polymeric optical components, even more particularly, thermooptical components, electro-optical components or passive components. The present invention pertains to an optical component having an at least pentalayered polymer structure on a substrate comprising: A) a low refractive index lower cladding layer, B) a core-matching refractive index lower cladding layer, C) a core layer, D) a core-matching refractive index upper cladding layer, and E) a low refractive index upper cladding layer. With this specific layer structure an optimal transversal confinement can be obtained, which results in less loss of light and an improved switching efficiency.
