Photonic crystals seen enabling optical circuits By Sara Sowah EE Times March 11, 2002 (11:40 a.m. EST) eet.com German researchers have developed a technique that could be used to construct tiny photonic crystals, enabling the construction of all-optical circuits. The team from Bonn University created a 3D interference pattern by shining a laser into a 'holographic crystal' and used the pattern as a stencil to position atoms from an atom laser. Professor Dieter Meschede, from the Institute of Applied Physics at the University of Bonn, said: "We have used the method of atom lithography with a complex light mask which, in principle, gives access to more complicated patterns than arrays of lines and dots.
