Abstract

We analyze the arrayed waveguide grating response on indium phosphide (InP) membranes on silicon (IMOS) technology. The model is based on an analytical approach (Kleijn et al. in Nat Photon 1:303–305, 2013) that provides a better accuracy than the Gaussian approximation for similar simulation times. Improved shallow to deep transitions to avoid possible layer misalignments are also presented and simulated.
