This work describes an innovative application of structures of photonic crystal slabs for gas sensors. Structures consisting in double ring have been studied by simulation. Their working mechanism is based in the effect of a given target gas in the pores of the slab. The effect pursued is to translate the variation of refraction index of the gas inside the pores into a shift in the position of peaks of transmission associated to resonances in the device
