Conformal graphene directly synthesized on intracavity whispering gallery mode microresonators for GHz repetition rate mode-locked lasers
We demonstrate tunable GHz-pulse fiber lasers by combining spectral filtering with conformal graphene. A microresonator filters modes, and graphene induces mode-locking, enabling pulses exceeding 150 GHz with up to 6.1 GHz tunability through graphene's photo-thermal effect.
