| 摘要 |
A miniaturized surface plasmon resonance (SPR) sensor is introduced for on-chip applications. The sensor's sensing surface is arranged in between a light source and detector. The structure facilitates building a SPR device on a chip. In one embodiment, a prism and light source are placed on top of a detector chip. In another embodiment, a self-mixing interferometer is incorporated to enable highly sensitive phase measurement. Other embodiments include SPR systems with integrated optical power monitors or on-chip microfluidic SPR systems.
