英文摘要	A multimode interference (MMI) polarization splitter with easy fabrication process was demonstrated in Silicon-On-Insulator substrate. The minimum device size, 8 mu mx1034 mu m was designed by Quasi-state imaging effect theory. Numerical simulations show that this optimized MMI polarization splitter has a good fabrication tolerance. The tolerance of width and length is +/- 0.04 mu m and +/- 10 mu m for transverse electric (TE) mode and +/- 0.14 mu m and +/- 35 mu m for transverse magnetic (TM) mode. The bandwidths are 20 nm and 80 nm for TE and TM respectively. Experiment results exhibits a -15 dB polarization extinction ratio bandwidth of 20 nm for the through-path and much wider for the cross-path. The extinction ratio and crosstalk achieve (-27.3 dB, -22.6 dB) for TE and (-26.6 dB, -23.9 dB) for TM.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000298796000005&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Engineering, Electrical & Electronic; Optics; Physics, Applied; EI; CPCI-S(ISTP); 2
