摘要:

We have investigated three different quasi‐phase‐matching approaches to second‐harmonic generation (SHG) in DANS (4‐dimethylamino‐4′‐nitrostilbene) poled polymer channel waveguides at 1.5 &mgr;m. Periodic photobleaching and periodically poled electrodes deposited directly on the film produced unacceptably high propagation losses. However, periodic electrodes on the substrate gave low losses and useful SHG. ©1996 American Institute of Physics.
