Abstract
In order to design three-port wavelength-division demultiplexer based on square lattice photonic crystal waveguide , wavelength-division demultiplexer was analyzed theoretically by using the characteristics of photonic band gap of photonic crystal and the transmission characteristics of slow light mode in photonic crystal , by using plane wave expansion method and finite difference time domain method .The spectral and spatial characteristics of wavelength-division demultiplexer were calculated numerically .The results show that adjusting the position of the column at the first row adjacent to the waveguide will change the frequency of slow light transmitted in three parts of waveguide .Based on the transmission characteristics of slow light , provided a reasonable structure design , the light beams at different frequencies can output from different output terminals , and the purpose of demultiplexing can be achieved .关键词
