We demonstrate tunable graphene nanoribbon-based photodetector for the wavelength range 5-12 µm. We leverage the width dependence of bandgap in nanoribbons, and their tunable plasmonic properties to demonstrate photodetection at room temperature. © Optica Publishing Group 2021, © 2021 The Author (s)
