In this paper, we fabricated the polymer waveguide type surface plasmon resonance (SPR) sensor using a white light source and optical spectrum analyzer (OSA). Fabricated sensor uses the principle of phase matching between evanescent wave and surface plasmon wave. According to the measuring result, the shift of resonance wavelength conducts the change of the refractive index. The proposed SPR sensor is expected to apply the integrated multichannel SPR sensor and the realtime monitoring system.
