Schematic of the cylindrical diffusing fiber, showing the four regions that are modeled. Photon packets are launched from the fiber core, with the diffusive medium being treated as having negligible absorption, and the cladding being treated as having negligible absorption and scattering. The dielectric reflector is treated as a perfect reflector.
