A time gating technique based on Four Wave Mixing was developed to measure for the first time the temporal profile of a 1D PhC nanolaser operating in the telecom range at room temperature. Our method enabled a resolution of 1 ps and a detection sensitivity of 200 nW peak power. Our results show a build-up time of the emission of around 30ps and a decay time of 35ps. This shows the potential of these nanolasers for encoding data at a high bit rate (15 GHz).
