Abstract:
The method of Finite Difference Time Domain ( FDTD) and directional coup ling theory of the medium waveguides are used as the basic theory. A field comes out through the inputwaveguide when the coup ler length is an integer multip le of the beat length. In the contrast, the field injected into one waveguide switches entirely to the other one if the coup ler length is an odd multip le of half the beat length. A three-wavelength photonic crystalmultip lexer is designed. And a method to compute the group velocity by the coup ler length is p resented also.
