| Abstract: | The integrated narrow band pass filter is an important photonic device. The performance of this device is limited by the two
problems, absorption coefficient and thickness homogeneous in the resonant cavity layer. We have developed a numerical simulation
method to analyze the factors’ influence on the behavior of integrated filters. It is found that the non-homogeneous of layer
thickness will play a dominance role in the property of band width of transmission spectra of the 32-chanels integrated narrow
band pass filter device in near infrared. |
