Photonic crystals (PhC) are a promising concept for new optical components. Passive devices in PhC, e.g. complex waveguides, are widely known, but for most applications active devices are required. One possible way to realize such devices is the functioning of 2D-PhC. This can be done by combining 2D-PhC with optical nonlinear (nlo) polymers. We present an experimental technique for the infiltration of individual pores which allows the realization of a broad spectrum of different designs. For the infiltration experiments we use 2D-PhC templates made of marcroporous silicon. After electrochemical deposition of a gold layer we use a focused ion beam machine and a mature infiltration technique for the infiltration of individual pores.
