A detailed 3-D finite-difference time-domain analysis of photonic crystal double-heterostructure bound state resonances is presented along with supporting experimental results. The connection between different photonic crystal waveguide bands and the associated photonic crystal double-heterostructure bound states is made, and mode profiles are presented. We analyze the quality factors using the Pade interpolation method and directional radiation properties by calculating the time-averaged Poynting vector. We also present field profiles of higher order bound states and discuss cavity geometries to enhance a given bound state mode relative to neighboring modes. Experimental lasing results are presented demonstrating the utility of our approach.
