Paper Abstract

To realize a high sensitivity gas sensor, a large wideband, temperature stabilized and large light confinement slow light structure in slotted photonic crystal waveguide (SPCW) is designed. The simulation results indicate that with a proper optimization of the SPCW structure, a very high group index of 105 can be achieved and the electric field enhancement factor would reach to 12. Combined with the correlation spectroscopy for signal processing, the detection limit of 10 ppm is achieved.
