Publikováno v: Journal of Nonlinear Optical Physics & Materials. 13:535-540

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
