We investigate the use of guided modes bound to defects in photonic crystals for achieving double resonances. Photoluminescence enhancement by more than 3 orders of magnitude is observed when the excitation and emission wavelengths are simultaneously in resonance with the localized guided mode and cavity mode, respectively. We find that the localized guided modes are relatively insensitive to the size of the defect for one of the polarizations, allowing for flexible control over the wavelength combinations. This double-resonance technique is expected to enable the enhancement of photoluminescence and nonlinear wavelength-conversion efficiencies in a wide variety of systems.
