Abstract

In this Letter, we demonstrate theoretically the design of a polarization-insensitive echelle grating demultiplexer on a nanophotonic silicon-on-insulator platform. The polarization-insensitive performance is achieved through a dual-grating system, which utilizes different concave gratings for different polarizations. The first concave grating acts as a polarization to beam splitter as well, allowing light with the other polarization to pass through and be reflected by the second grating, which is designed separately; thus the same spectral responses are obtained for the two polarizations.
