Two Dimensional Photonic Crystal

We present a new concept to adjust the transmission properties of a two-dimensional photonic crystal by photobleaching the structure. A square lattice of 500 nm lattice constant and 300 nm hole diameter was fabricated by etching air holes into a slab waveguide consisting of a polymethylmethacrylate polymer covalently functionalized with 10 mol% of the nonlinear Disperse Red 1 chromophore. While illuminating the photonic crystal with UV light the azo molecule bonds degenerate, resulting in a considerable refractive index change and a reduced slab waveguide core layer thickness. Wavelength and polarization dependent measurements show a very large shift of the dielectric band edge of 35 nm in TE and of 27 nm in TM polarization. With our novel concept it is possible to compensate fabrication inaccuracies and to trim photonic crystal transmission properties.
