We describe experiments to measure the spatial and the temporal distribution of photons traversing a turbid medium in the early-arriving regime in which the photons are multiply scattered but are not completely randomized. The photon paths are resolv

We show that light transport in a turbid medium can be described by a path integral with a quasi-particle Lagrangian. The most probable trajectory over which photons can be found can be obtained from this Lagrangian. This approach extends the diffusi

The nature of guided modes and defect modes in periodic dielectric waveguides is investigated computationally for model systems in two dimensions. It is shown that defect states that exist within the band gap of guided modes can be excited to form ti
