The paper deals with the modeling, based on the Finite Difference Time Domain method, of active two-dimensional photonic crystals. The onset of laser oscillation is observed by simulating the active substance as having a negative frequency-dependent Lorentzian-shaped conductivity so including into Maxwell's equations an electric current density. The properties of the active two-dimensional photonic band gap structures are evaluated in presence of gain saturation effects.

Abstract
The paper deals with the modeling, based on the Finite Difference Time Domain method, of active two-dimensional photonic crystals. The onset of laser oscillation is observed by simulating the active substance as having a negative frequency-dependent Lorentzian-shaped conductivity so including into Maxwell's equations an electric current density. The properties of the active two-dimensional photonic band gap structures are evaluated in presence of gain saturation effects.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
