Paper Abstract

To find a detecting method that can be applied to the clinical screening and diagnosis, the cascaded micro-ring sensor with Vernier effect was used to distinguish gastric cancerous and normal cells. The simulation by FDTD of the cascaded microring sensor with different refractive indexes of the analyte (normal cells and gastric cancer cells) will be presented. In the simulation, with the refractive index’s change Δn=0.02 for the two different analyte, the shift of sensor’s resonant wavelength is 6.71nm. And the cascaded micro-ring sensor’s sensitivity S is 335.5nm/RIU, and it is much larger compared to 19nm/RIU for a single ring sensor.
