1. A sensor comprising:

  • a) a substrate with a first refraction index;

    b) a planar waveguide formed on the substrate and having a second refractive index larger than the first index, the waveguide including a light emitting material and at least one linear micro-resonator structure on a waveguide surface opposite to the substrate, the micro-resonator structure operative to output a light signal that includes a spectral response to an interaction between a target substance and the micro-resonator, the light being emitted upon optical pumping of the light emitting material.
