1. A monolithically integrated biochip for testing biological substances comprising a plurality of binding sites, optical means for determining a specific binding event at each binding site, wherein the plurality of binding sites are monolithically integrated by processing one substrate with the optical means for determining a specific binding event which comprise at least one microcavity light source, at least one photodetector and at least one planar waveguide, an evanescent field of light propagating in the waveguide interacting with the biological substance under test, and wherein the microcavity light source is a photonic band gap microcavity light source.
