摘要：

We present an idea of grating-based plasmon biosensor utilizing phase detection to realize high resolution in finding a refractive index of a material put on the surface of a metal grating. Considering a trade-off between high resolution and experimental practicability, we show a table of recommended setup that covers a wide range of the index. Keeping the diffraction efficiency no less than 10(-3) and assuming the resolution in phase detection to be 2.5 x 10(-2) degrees, we estimate the resolution of the biosensor as 7.5 x 10(-7) refractive index units. We also discuss the possible improvement to realize a predicted superior limit of resolution around 10(-8) refractive index units.
