Photonic circuits with tungsten oxyselenide (TOS)-doped graphene placed on circular ring resonators.

Caption

The TOS-doped graphene is highly conductive but absorbs very little of the infrared light in the resonator—a combination of properties that makes this material unique and promising for opto-electronic applications.
