Nanostructured materials in photonics are mainly built by lithographic techniques. This approach requires a complex and expensive technology. An alternative approach is based on self-aggregating materials, like porous alumina that aggregates in periodic structures. Porous alumina is a promising material with a view to a massive and cost affordable manufacturing by electrochemical processes. The design of alumina-based photonic devices is an essential requirement for the development of a manufacturing process. In particular, in this work we address the numerical modeling and the characterization of a device exhibiting the superprism phenomenon, which is suitable for wavelength division multiplexing applications.

Abstract
Nanostructured materials in photonics are mainly built by lithographic techniques. This approach requires a complex and expensive technology. An alternative approach is based on self-aggregating materials, like porous alumina that aggregates in periodic structures. Porous alumina is a promising material with a view to a massive and cost affordable manufacturing by electrochemical processes. The design of alumina-based photonic devices is an essential requirement for the development of a manufacturing process. In particular, in this work we address the numerical modeling and the characterization of a device exhibiting the superprism phenomenon, which is suitable for wavelength division multiplexing applications.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
