This paper introduces the concept, research methods and application of photonic crystals. Starting from Maxwell's equations, the functional form of the TE mode and TM mode of the 2D crystal is derived. In 2D crystal, according to the functional forms, we conduct some stimulation about two-demensional photonic crystal with line-defect and dot-defect, forming some results as following: 1. obtaining the spectrum distribution of the photonic crystal with line-defect and with T-defect; 2. As to photonic crystal with dot-defect, we get the spectrum distribution of the dot, which can be used in WDM; 3. We combine the photonic crystal with dot-defect with the one with line defect, and obtain the spectrum distribution of the dot, as showing, which can be used in a filter.
