Abstract
Efficient blue and green SHG devices are important for high-density optical recording, laser printing and optical measurement systems as a high energy photon source. In particular, waveguide device is advantageous because of its high conversion efficiency, compactness, and variety of phase-matching technique. Organic SHG materials have been potentially attractive due to their large χ(2)[1]. However, practical disadvantages of organic materials remain such as efficiency/transparency trade-off and undeveloped device-processing technology.
