MICROCABIDADES OPTICAS Y ESPONJAS FOTONICAS, PROCEDIMIENTO DE PRODUCC ION Y SUS APLICACIONES EN LA FABRICACION DE DISPOSITIVOS FOTONICOS.

摘要

The invention concerns a microsphere of silicon with a diameter between 0.1 and 50 micras capable of functioning as an optical microcavity with Mie resonant modes for wavelengths in the range between 1 and 15 micras, and a photonic sponge formed from the former. Preparation thereof is achieved by means of a simple method based on the decomposition by heating of the gaseous precursors. The use of these microspheres and photonic sponges are useful for manufacturing photonic devices, for example, solar cells, photo diodes, lasers and sensors.
