[摘要]：We report on the experimental characterization of the thermal sensitivity of biosensors based on the coupling of Bloch surface waves (BSW) on amorphous silicon nitride/silicon one dimensional photonic crystals (1DPC). The results show that the silicon alloys compensate the thermo-optic effect taking place in the external medium and indicate that a class of temperature insensitive biosensors can be fabricated by properly designing the layout of the 1DPC. The experimental results are in very good agreement with numerical simulations based on a transfer matrix approach. Moreover, the BSW biosensors show a resolution of 0.03 degrees C for the measurement of temperature. (C) 2011 American Institute of Physics. [doi:10.1063/1.3666031] |
