  In this work we have studied the optical properties of disordered photonic
structures, in which we have controlled the distribution of the random layer
thickness. Such structures are characterized by an alternation of high and low
refractive index layers, but the layer thicknesses follow the aforementioned
distributions. We have used two types of distribution: a distribution in which
each thickness has the same probability to occur and one in which the thickness
follows a Gaussian function. We have simulated the average transmission all
over the spectrum for photonic structure characterized by a different width of
the distribution. We have found that the choice of the distribution of the
layer thickness is a control of the average transmission of a random photonic
structure.
