Optical devices based on molecular azo glasses...

Nanometer-sized corrugation gratings that act as light couplers and resonators are produced holographically by subjecting a glassy film of an azo dye to crossed circularly polarized argon laser beams. The gratings are remarkably long-term stable even under electrical stress and can easily be integrated into multilayer organic optical devices (A. Perschke, T. Fuhrmann, Adv. Mater. 2002, 14, 841-843).
