This paper reviews recent advances in graphene active plasmonics and their applications to terahertz lasers and sensors. We theoretically discovered and experimentally manifested that when the carrier population in graphene is inverted the excitation of graphene plasmons results in propagating surface plasmon polaritons with giant gain in a wide THz range. Furthermore, when graphene is patterned in a microribbon array by grating gate metallization, the structure provides super-radiant plasmonic lasing with giant gain as well as ultrahigh sensitive detection at the plasmon modes in a wide THz frequency range..
