Modeling of three-dimensional photonic crystal lasers in a frequency domain: A scattering matrix solution
We derive a light-intensity-dependent dielectric constant for a gain medium based on the conventional rate equation model. A scattering-matrix method in conjunction with an efficient iteration procedure is proposed to simulate photonic crystal lasers (PCLs). The light output vs pumping (L-I) curve, lasing mode profile, and chirping effect of the lasing wavelength {lambda}{sub L} can be calculated. We check our method in a one dimensional distributed Bragg reflector laser and simulate a complex three dimensional woodpile PCL to test the capabilities of our model. We found that PCLs with a more uniform field distribution in the gain media will have higher L-I slope efficiencies as well as more stable lasing wavelengths {lambda}{sub L}.
