Response to 'Comment on Tunable terahertz-mirror and multi-channel terahertz-filter based on one-dimensional photonic crystals containing semiconductors'' [J. Appl. Phys. 110,073111 (2011)]

摘要

In our previous paper, we have designed a tunable terahertz mirror and a multi-channel terahertz filter based on one-dimensional photonic crystals (1DPCs) containing semiconductors. By adopting the transfer matrix method (TMM), it is indicated theoretically that the THz mirror is tunable by changing the external temperature or the thickness of the components of the 1DPC and the operation frequency of the multichannel filter can be tuned by changing the temperature and thickness of the component materials in the 1DPC. Moreover, it is found that the channel number of the filter can be controlled by varying the number of the defect layers in the 1DPC, and the transmittance bandwidth can be adjusted by changing the period number of the 1DPC.
