英文摘要	An ultrasensitive surface plasmon resonance (SPR) refractive index detection scheme based on weak value amplification is presented. Extremely low refractive index change (9.8 x 10(-7) RIU) of sodium chloride solution was readily measurable, with a resolution of 1.3 x 10(-7) RIU, a nearly three orders of magnitude increase in sensitivity over conventional SPR index-sensors via intensity interrogation. Preliminary measurement of refractive index change of alcohol solution demonstrated a minimum of 4.0 x 10(-6) RIU with a resolution of 3.7 x 10(-7) RIU, better than those obtained through wavelength-modulated heterodyne interferometry (with a resolution of 1.5 x 10(-6) RIU). The system is highly stable, having a simple and compact configuration, lending to easy and repeatable operation in standard ambient environment.
