Evanescent coupling is used to couple light from an organic Lambertian emitter into a single mode planar waveguide. Either an organic light emitting diode (OLED) directly excites the waveguide mode or an OLED pumps a photoluminescent (PL) material layer located directly on the waveguide. At the out-coupling grating the guided light is diffracted onto an array of organic photodiodes acting as a spectrometer. A spectral resolution of down to 16 nm could be achieved with integrated optoelectronic system.
