Spectral Trimming of Photonic Crystals
We present a novel concept to trim the transmission properties of finite two dimensional photonic crystal slab waveguide structures by UV photobleaching. Systematic fabrication inaccuracies may be compensated due to the shift of the spectral properties during the bleaching process. To prove our concept experimentally, we measured the transmission of UV sensitive photonic crystal structures for different doses. A shift of band edges and defect resonance peaks depending on UV dose is observed due to changes in refractive index and geometry.
