Abstract
A nonconventional wavelength-selective grating-assisted vertical coupler is proposed and analysed. Its novelty consists in the grating position: neither between nor above the waveguide cores, but in a lateral region. Analytic and numerical results indicate that, for devices that are not yet optimized, frequency selectivity and/or device length are at least comparable with those of conventional grating-assisted filter-couplers. Potential advantages of the new device, in terms of performance and of manufacturing technology, are discussed.
