The present disclosure relates to a nanolaser generator using a transparent graphene electrode, a method for manufacturing the same, and a single nanopillar LED using the same. The nanolaser generator includes a microdisk resonator, a protruding dielectric ring provided to surround a boundary surface of the microdisk resonator, an external dielectric ring provided at an outer side of the microdisk resonator, and a transparent graphene electrode provided at upper surfaces of the microdisk resonator, the protruding dielectric ring and the external dielectric ring. Therefore, the processes required for generating a nanolaser may be reduced by half in comparison to a general technique, and a nanolaser may be generated just with a micro current.
