Abstract
Some implementations described herein include a photonics integrated circuit device including a photonics structure. The photonics structure includes a waveguide structure and an optical attenuator structure. In some implementation, the optical attenuator structure is formed on an end region of the waveguide structure and includes a metal material or a doped material. In some implementations, the optical attenuator structure includes a gaussian doping profile within a portion of the waveguide structure. The optical attenuator structure may absorb electromagnetic waves at the end of the waveguide structure with an efficiency that is improved relative to a spiral optical attenuator structure or metal cap optical attenuator structure.
