  text: The device principle of a prism-based on-chip spectrometer for TE polarization
    is introduced. The spectrometer exploits the modal dispersion in planar waveguides
    in a layout with slab regions having two different thicknesses of the guiding
    layer. The set-up uses parabolic mirrors, for the collimation of light of the
    input waveguide and focusing of the light to the receiver waveguides, which relies
    on total internal reflection at the interface between two such regions. These
    regions are connected adiabatically to prevent unwanted mode conversion and loss
    at the edges of the prism. The structure can be fabricated with two wet etching
    steps. The paper presents basic theory and a general approach for device optimization.
    The latter is illustrated with a numerical example assuming SiON technology.
