Incoherent Propagation of Light in Coherent Models
Publié en 2013
In the finite element based modeling and simulations only the coherent propagation of light is considered. However, in reality when light passes the thick layer it loses the phase information and its coherent nature due to the spatial, temporal or spectral incoherence. In this work, we present two methods to include the incoherent layer in coherent based simulations: (a) phase matching and (b) phase elimination approach. Additionally, appropriate scaling down of incoherent layer thickness from mm range to few hundred nm range is shown. Methods are implemented in COMSOL Multiphysics® and verified on bare glass substrate and on complete thin film amorphous silicon solar cell in superstrate configuration.
