英文摘要	terahertz (thz) wavelength division demultiplexer based on a compact defects-coupled photonic crystal waveguide is proposed and demonstrated numerically. this device consists of an input waveguide that perpendicularly coupled with a series of defects cavities, each of which captures the resonance frequency from the input waveguide. coupled-mode theory and finite element method are used to analyze the transmission properties of the structure. it is found that the transmission wavelength centered around 1thz can be adjusted by changing the geometrical parameters of defects cavities, which equals to thz waves generated by optical methods such as difference frequency generation and optical rectification. applications in this frequency range are urgently needed. furthermore, the highest transmission efficiency of 0.94 can be achieved when a perfect wavelength-selective mirror is set in the output waveguide.
