(a) G-SWG divided into three areas, with graphene transferred only onto Area 2 of the SWG. (b) Left: Simulated spectrum evolution in G-SWG (left). Right: Simulated on-chip OFC spectra with (blue) and without (black) graphene on the SWG for propagation lengths of 0.3, 0.5, and 2 mm (right). (c) Left: Simulated spectral evolution in Area 2 of the G-SWG. Right: On-chip OFC spectrum in Area 2 of the G-SWG for the graphene length LGr of 100 (blue), 200 (red), 300 (green), and 400 μm (light blue) and without graphene on the SWG (black).
