New Etching Method to Produce Three-dimensional
Microstructures in Silicon for the Processing of Light Signals in
Telecommunications
In modern telecommunications, light carries digital
information over kilometers within seconds. Adapted optical materials con-trol
the light signals. In the AFM journal, researchers from Ber-lin, Louvain, and
from Karlsruhe Institute of Technology present a method to produce photonic
crystals. Their optical properties are adjusted by structures of micrometer
size. The method is rapid, cheap, and simple and partly uses the self-organization
principle
