Dear meep users and Dr. Steven Johnson, I would like to see optical bistability in 1-D photonic crystal. therefore I have used a paper in this field, http://www.sciencedirect.com/science/article/pii/S0030401802016899. I defined a 1-D photonic crystal which consist of alternative layer of materials with high and low dielectric constant. a Kerr medium is sandwiched symmetrically between two same PCs. then I have defined single-frequency source with trigonometric shape. I have chosen chi3 = (4/3)*3e-8*n^2 for nonlinear material but I really get confused about how to choose the amplitude of my source to see optical bistability. when I am choosing amplitude of my source 1MW I see a noisy output intensity. I have seen previous answer of steven for similar question: http://www.mail-archive.com/meep-discuss@ab-initio.mit.edu/msg00402.html but I still have a few question about what steven have said, 1-is the method steven said work for trigonometric source? 2- which meep flux function should use for measuring the power? 3-for instance if we use (flux-in-box...) or (electric-energy-in-box....) , we must calculate it in hole photonic crystal volume or in a limited plane just after the source or at the end of photonic crystal? I am very thankful if you could help me in this field. I desperately need to answer these questions. regards, taimaz,
