Modeling in Optics: Observation, Postulation, Modeling (Meaningful in Physics), Justification, Prediction

Abstract
The properties of lights we know nowadays, for example the diffraction of lights and polarizations of lights were well described by electromagnetic theory, namely, the Maxwell,s equations. By tracking the development of optics, we should be able to acquire how physicists established models having been cycling among the phases of observation, postulation, modelling and justification. Moreover we are also going to see how these models helps the development of new knowledge such as the prediction of the theory and models in nonlinear optics. To further elucidate optical modelling, the formation of “crescent waves” in vertical cavity surface emitting laser (VCSEL) and vortex beam in a an azimuthal symmetry-breaking degenerate optical cavity are modeled, respectively to understand the interesting nonlinear dynamics in lasers and to propose new possibilities in the related field.
