Abstract
A photonic integrated circuit device can comprise one or more layers having different refraction indices that cause optical coupling issues and losses from layer variations. A film of material can be applied to a layer of the photonic integrated circuit to avoid the issues to increase the optical bandwidth of the photonic integrated circuit device and decrease sensitivity to manufacturing and design processes.
