Device layout and waveguide simulation. (a) Schematic cross-section of the graphene waveguide-integrated thermal emitter after encapsulation. The electrical connection scheme illustrates the Joule heating method to generate thermal emissions. (b) Schematic top view of the components of the PIC. (c) False-colored scanning electron micrograph before encapsulation. (d) Simulated electric field profile of the fundamental TE mode of the waveguide, including relevant materials.
