- Surface relief gratings
A novel organic distributed-feedback laser with programmable lasing wavelengths is described. The laser is based on a double-layered structure composed of an azopolymer layer that forms a surface relief grating (SRG) and a dye-doped polymer layer that provides optical gain. The lasing wavelength is programmed by erasing and rewriting the azopolymer SRG with an interference pattern of a different period (see Figure).
