The Design and Analysis of Wavelength-Mode Division Multiplexer/Demultiplexer
摘要
Abstract
To further improve the communication capacity,a wavelength-mode division multiplexer/demultiplexer based on photonic crystals is proposed.Consisting of four combination resonator,four wavelength selective reflection cavities,and a pair of asymmetric parallel waveguides for mode conversion,the wavelength-mode division multiplexer/demultiplexer is realized by adj usting the radius and refractive index of the cavity as well as the width and the coupling length of the asymmetric parallel waveguide.Finite Difference Time Domain (FDTD)methods are used to simulating the performance of mode division multiple-xer/demultiplexer.Numerical simulations show that the designed device has the potential for high-capacity Wavelength Divi-sion Multiplexing-Mode Division Multiplexer (WDM-MDM) optical communication systems with a low insertion loss<0.11 dB and a low mode crosstalk <-16 dB,which can meet the requirements of today''s large capacity optical communica-tion system.关键词
