TLDR
In this article, a polymeric optical component having an at least penta-layered polymer structure on a substrate comprising: A) a low refractive index lower cladding layer, B) a core-matching lower claddings layer, C), a core layer, D, a corematching upper clatterers layer, and E) a lower refractive indices upper cladderers layer is presented.Abstract:
The present invention is in the field of optical components, more particularly, polymeric optical components, even more particularly, thermo-optical components, electro-optical components or passive components. The present invention pertains to an optical component having an at least penta-layered 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.read more
