Abstract
Provided is a photonics device including at least two arrayed waveguide grating structures. Each of the arrayed waveguide grating structures of the photonics device includes an input star coupler, an output star coupler, and a plurality of arrayed waveguides optically connecting the input star coupler to the output star coupler. Each of the arrayed waveguides includes at least one first section having a high confinement factor and at least two second sections having a low confinement factor. The first sections of the arrayed waveguides have the same structure.
