Based on the evanescent wave resonance, a photonic crystal sensing structure with air slot-porous silicon-air slot Fabry–Perot cavity (F–P cavity) is proposed. Taking the F–P cavity as the sensing unit, when the gas to be detected is filled into the sensing unit, the refractive index of the air slot will be changed and the refractive index of the porous silicon layer will also be varied, both of which will shift the resonant peak and greatly increase the sensitivity of the sensor. By adjusting the structural parameters, the quality factor (Q value) can be optimized. A model for the relationship between the resonant wavelength and the refractive index of the detected organic gas was established, and the refractive index sensing performance was analyzed. The results show that the Q value of the structure can attain to 12312.2 and the sensitivity is about 8661.708 nm/RIU, which can provide effective theoretical reference and technical guidance for organic gas detection with low concentration.

Abstract We present a multichannel sensor for the simultaneous monitoring of three different samples. established from a one-dimensional photonic crystal, this device is formed by an alternating layer of silicon dioxide (SiO2) and titanium dioxide (TiO2) with three defect layers containing the samples to be monitored. Numerical studies claim that three transmission peaks appear in the bandgap, these transmission peaks are caused by the three samples infiltrated in the defect layers. In real-time detection purposes, it is possible to exploit these transmission peaks. In addition, peak frequencies have the advantage of being susceptible to sample concentrations. With this photonic structure, a sensitivity of 800 nm per unit of refractive index (RIU) is reached.
