We report a novel approach to spectroscopy of surface plasmons based on the simultaneous excitation of surface plasmons by a polychromatic light and the dispersion of light on a diffraction grating coupler of a special design. This approach shows promise for the development of new, miniaturized, spectroscopic surface plasmon resonance (SPR) sensors. Potential of this approach for SPR sensing is demonstrated in a model refractometric experiment.
