We demonstrate an ultra-high efficiency and fast graphene microheater on silicon photonic crystal waveguide. By taking advantage of slow-light effect, a tuning efficiency of 1.07 nm/mW and power consumption per free spectral range of 3.99 mW. A fast rise and decay times (10% to 90%) of only 750 ns and 525 ns are achieved. The corresponding figure of merit of the device is 2.543 nW·s, one order of magnitude better than results reported in previous studies.
