Varying the Effective Refractive Index to Measure
... We prove that the same symmetry between frequency and effective refractive index variation holds for the intensity correlation function (3). The basic ingredients for deriving this correlation function are the average Green’s function (2) and an irreducible scattering vertex [4]. We symbolically den ...
