The effect of a defective mode layer of GaAs semiconductor material of one-dimensional nonlinear photonic crystal, which is a function of intensity as well as the wavelength, is numerically simulated using transfer matrix method. It is observed that the transmission efficiency of this defective layer increases with an increase in the wavelength of the material. At the first transmission window (820 to 910 nm), the transmittance is low, but at the second (1260 to 1360 nm) and third transmission windows (1530 to 1565 nm), it approaches 100%. At the first transmission window, the efficiency of the material approaches 100% with an increase in the intensity up to 140 GW / cm2. We have designed a tunable 8-channel dense wavelength division multiplexer for both (first and third) transmission windows and compared the quality factor and efficiency of the structure and found that the transmission efficiency of the defective layer of the third transmission window is better than first transmission window. We observed that the channel spacing for first and third transmission windows are 0.72 and 1.17 nm, respectively, which correspond to the International Telecommunication Union grid systems.

8通道可调DWDM的设计使用缺陷模式非线性光子晶体覆盖了所有传输窗口

一维非线性光子晶体的GaAs半导体材料的缺陷模式层的影响，是强度和波长的函数，是使用转移矩阵法进行数值模拟的。可以看出，该缺陷层的透射效率随着材料波长的增加而增加。在第一个透射窗口（820至910 nm）处，透射率较低，但是在第二个透射窗口（1260至1360 nm）和第三个透射窗口（1530至1565 nm）处，透射率接近100％。在第一个透射窗口处，材料的效率接近100％，强度提高到140 GW / cm2。我们针对（第一和第三）传输窗口设计了一个可调的8通道密集波分复用器，并比较了结构的品质因数和效率，发现第三传输窗口的缺陷层的传输效率比第一传输窗口好。传输窗口。我们观察到，第一和第三传输窗口的信道间隔分别为0.72和1.17 nm，与国际电信联盟网格系统相对应。
