A group of professors from the departments of Chemistry, Soil Science, Physics and Applied Mathematics of the University of Navarra is working together in the preparation and characterization of a type of material termed “photonic crystals”, which has optical properties with many uses. Thanks to these crystals, in the future more powerful and effective lasers will be able to be constructed. Indeed, the Nobel prize winner of 2005 has made specific mention of recent progress in laser technology, which demonstrates the growing interest in this scientific field.
These crystals are required to have a periodicity of an optical magnitude. This feature means that these materials have a structure of energy bands for photons similar to that which metals possess for electrons. These crystals provide ideal characteristics for the development of instruments with important applications in such diverse areas as communications, optical electronics and medicine.
Current tendencies point towards miniaturization, for creating instruments which are both faster and smaller. This will permit enormous advances in nanotechnology.

Quantum optical sensor for the first time tested in space – with a laser system from Berlin
23.01.2017 | Ferdinand-Braun-Institut Leibniz-Institut für Höchstfrequenztechnik
For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...
An important step towards a completely new experimental access to quantum physics has been made at University of Konstanz. The team of scientists headed by...
Yersiniae cause severe intestinal infections. Studies using Yersinia pseudotuberculosis as a model organism aim to elucidate the infection mechanisms of these...
Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
