    "abstract": "We present the design, fabrication and preliminary experiments of\ntwo-dimensional photonic crystal cavities made in nanoporous silicon\nluminescent at 700-800 nm. Enhancement in photoluminescence extraction\nefficiency at the resonant wavelength is expected due to Purcell effect and\ndirected radiation pattern defined by the cavity. Such cavities should also\nenhance nonlinearities exhibited by porous Si beyond what is observed in\none-dimensional distributed Bragg reflection cavities due to their small mode\nvolumes and modest quality factors. This design aligns itself well to\nintegration with conventional silicon based electronics on a single chip.",
