  title = {Picosecond differential transmission measurements on porous silicon},
  abstract = {<p>In this work, differential transmission measurements are made to characterize the short-time-scale optical properties of p-type light-emitting porous silicon. Aged and freshly etched samples are used to determine the impact of aging on the nonlinear optical properties. Two-component photo-induced absorption is observed in both types of samples. A model that considers porous silicon's unique properties of confinement, high surface area, and disorder on several length scales is presented to explain the experimental results.</p>},
