Abstract:

The light propagation characteristic in onedimensional function photonic crystal with metal defect was studied by transfer matrix, and compared with that of the function photonic crystal without defect layer, showing electric field intensity enhance obviously. We researched the effects of the position and the number of defect layers on electric field distribution. Then we studied the electric field distribution via changing the half period numbers.

Key words: function photonic crystals, transfer matrix, defect layer, electric field distribution
