Abstract: (3807 Views)
In this paper we proposed an optical demultiplexer based on photonic crystals. The cross section of the structure is 355μm2 so it can be a suitable candidate for designing optical integrated circuits. In the proposed structure, we used two cavities capable of selecting output central frequency with adjusting radius of rods as defects in photonic crystals. The transmission efficiency of proposed demultiplexer is above 70% and the quality factor is better than 1000. The average bandwidth of output spectra is about 1.25nm and the crosstalk level is -14.5dB.
