我们证明了超快退相的随机传输光通过一个层组成的强散射GaP纳米线。移相导致单个伪模的非线性强度调制，其比体GaP的强度调制大100倍。不同的贡献，非线性响应分离使用总传输，白光频率相关性，统计伪模分析。发现退相时间为。数值模型计算包括光致吸收和单个散射体的变形，两者定量吻合。光子本征模的非线性退相为随机激光器、纳米光子开关和光子定位的超快控制开辟了途径。
We demonstrate ultrafast dephasing in the random transport of light through a layer consisting of strongly scattering GaP nanowires. Dephasing results in a nonlinear intensity modulation of individual pseudomodes which is 100 times larger than that of bulk GaP. Different contributions to the nonlinear response are separated by using total transmission, white-light frequency correlation, and statistical pseudomode analysis. A dephasing time ofis found. Quantitative agreement is obtained with numerical model calculations which include photoinduced absorption and deformation of individual scatterers. Nonlinear dephasing of photonic eigenmodes opens up avenues for ultrafast control of random lasers, nanophotonic switches, and photon localization.
