Paper Abstract

Silicon hybrid photonics has attracted in the last years a growing interest for the integration of various materials within silicon photonics. In this picture, hollow-core slot photonic crystal waveguides play an important role as they allow an efficient overlap between the high electromagnetic power density of propagating modes and the introduced materials. Besides this potential advantage, part of the cost to pay is that light coupling into such waveguides from strip waveguides becomes difficult. We propose here a strategy in order to efficiently side-couple light into such slow light modes, leading to a typical 80% efficiency at nG=30.
