    Abstract

    We demonstrate an optical sensor that consists of an amplifying organic semiconductor waveguide with a protective polymer cladding for photostability. Sensing is achieved by evanescence of the guided amplified spontaneous emission (ASE) combining high signal levels at detection with simplicity of implementation. We show correlations between the presence and concentration of colloidal semiconductor nanoparticles on the cladding surface and changes in both the ASE threshold and the optical gain.
