摘要：
Transmission characteristics of one-dimensional photonic crystal structure with a defect have been studied. We consider a Si/air multilayer system. We also consider the refractive index of Si layer to be dependent on temperature and wavelength simultaneously. Central wavelength of the defect mode depends on the width of the defect layer, so we can change the central wavelength of defect mode by changing the width of defect layer. This property can be exploited in the designing of wavelength division demultiplexer for optical communication. (C) 2012 Elsevier GmbH. All rights reserved.
