Abstract
An optical quantitative detection device comprising: a nonlinear waveguide sensor having a top cladding layer with a top surface for interacting with a target molecule; a second waveguide; a second cladding layer optically coupling the nonlinear waveguide sensor to the second waveguide. Wherein optical excitation of the sensor and optical excitation of the second waveguide enables quantitative discrimination of a target molecule.
