Abstract
To Construct the one-dimensional three sects photonic crystal with symmetrical structure in the form of (AB)N1 (BA)N2, a numerical calculation is conducted using the transfer matrix method of photonic crystal. It is found that in the main prohibitive bands of transmission spectrum there are extremely narrow single transmission peaks. The changing laws of the transmission peak position λ with the changes of the period quantities Ni (i=1,2), the refractive rate nj (j=1,2,3) and the thickness a, b and c are analyzed. It is concluded that they can be approximately considered as linear in a small range and N1 = N2 = 7 is the optimal period quantities in theory. Based on these characteristics, through the adjustment of the parameters, the light needed is distilled in the mixing light in the range of 2280~2396 nm. The result is satisfactory.
