Ultra-high sensitive integrated optical sensor based on triangular resonator with surface plasmon resonance

摘要：

　　We have proposed surface plasmon resonance(SPR)-combined triangular resonator for ultra-high sensitive sensor.InP-based triangular resonator,in which a gold thin film for SPR phenomenon is applied on a total internal reflection mirror,is designed and optimized by finitedifference time-domain method and analytical calculation.Due to the large phase shift according to refractive index variation in the SPR condition,a significantly enhanced sensitivity of 930 nm/RIU have been obtained at the SPR angle of 24.125° and the gold film of 33.4 nm.
