Tuneable microcavities embedded in woodpile photonic crystals were generated by femtosecond-laser direct writing in a solid polymer. Analogous to a simple Fabry-Perot etalon cavity size and angular dependence were observed experimentally and confirmed using supercell calculations. The addition of one and two-dimensional lattices to the cavity allows for additional fine-tuning.
