Abstract :
We describe a coupler that consists of two phase-mismatched polymer waveguides coupled together by a tapered AlAs/AlGaAs vertical cavity structure. At any particular wavelength, the light is transferred from one polymer waveguide to the other via the semiconductor cavity at a unique position along the waveguide. Thus, the length of the device determines the range of wavelengths transferred. In addition to a wavelength router, the structure could be useful for wavelength selective amplifiers or multiwavelength lasers. The concept is demonstrated in a passive structure with a resolution of about 1 nm.<>
