Photonic stopband tuning of organic semiconductor distributed feedback lasers by oblique angle deposition of an intermediate high index layer
M. Stroisch, C. Teiwes-Morin, T. Woggon, M. Gerken, U. Lemmer et al.
We modified the photonic band structure of organic distributed feedback lasers by introducing a patterned high index intermediate layer of tantalum pentoxide. This layer was oblique angle evaporated onto one dimensional surface gratings with a periodicity of 400 nm. The dielectric broadened the stop ... [Appl. Phys.
