Ovens and furnaces for sedimentation and thermal treatments
Climatic chamber
Magnesioredution crucible

Characterization

¡Hola mundo!

The Photonic Crystals Group is a multidisciplinary team doing basic research in photonic crystals and related systems. While Materials Science is capital in our research some Fundamental Physics aspects are also central.

Our main interest is photonic crystals, which we realize by means of opals. We cover the synthesis and processing of materials and study light transport, generation and interference in ordered and disordered dielectric structures.
