We present the local polymer infiltration of planar photonic crystal cavities via a maskless laser-writing technique. After the infiltration of the air holes with a UV-curable monomer a focused laser is used to locally polymerize the monomer in selected holes at the cavity boundaries. We show that cavity modes with different symmetries can be differently tuned depending on the size and the position of the infiltrated region around the cavity. © 2008 Optical Society of America.
