Paper Abstract

In this paper, we investigate the possibility of vertically interconnecting waveguides on different substrates using grating couplers. The coupling between waveguides is achieved using a holographic projection scheme. The effects of alignment and fabrication tolerances, as well as the dispersion characteristics, of this structure are considered. Simulation results show that this type of interconnection is surprisingly insensitive to fabrication errors.
