摘要
A TM-pass polarizer based on multilayer graphene polymer waveguide is proposed and theoretically analyzed.The mode properties,the extinction ratio,the insertion loss and the bandwidth are also discussed.The results show that a TM-pass polarizer,which only guides the TM mode,can be achieved by multilayer graphene polymer waveguide.With length of 150μm,the proposed polarizer can achieve extinction ratio of 33 dB and insertion loss of 0.5 d B at optical wavelength of 1.55μm.This device has an excellent performance,including large extinction ratio and low insertion loss within the spectral range from 1.45μm to 1.6μm.
