| Abstract: | An all-dielectric fabry-perot interference filter is illuminated by a laser pulse, absorption of optical energy in the absorptive layers and the diffusion of the resulted heat throughout the multilayer structure are studied. Numerical solution the heat diffusion equation under appropriate boundary conditions by box difference formula are used. The method and the obtained results are helpful to understand thermo-optic bistability phenome- non in all-dielectric interference filter. |
