Abstract
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 stopband due to its high refractive index compared to both the substrate and the active layer. By tuning the layer thickness we could increase the stopband from 3 to 16 nm.
