Observed spontaneous THz emission(1-7.6THz) at 100K by current injection in distributed-feedback dual-gate graphene transistor. We saw nonlinear threshold-like behavior w.r.t the current-injection level. Precise DFB cavity design is expected to transcend spontaneous emission to stimulated emission.
