英文摘要	We experimentally demonstrate a novel ultrabroad-band and wide-angle unidirectional coupling scheme by combining the coupling effect of single nanoslit and chirped grating effect. The operation principle is numerically and experimentally clarified through analysis and compare. Numerical analysis shows that the fabricated chirped-nanoslits grating could unidirectionally couple surface plasmon polaritons from free-space light over an ultrabroad-band (1.3 mu m) and wide-angle (30 degrees) ranges. Excellent unidirectional coupling performance with extinction ratio ER > 10 dB (a peak value ER = 22 dB) over an ultrabroad operating bandwidth of 300 nm and wide angular range of 26 degrees is experimentally demonstrated.; National Natural Science Foundation of China (NSFC) [61320106001, 61227014]; SCI(E); ARTICLE; 14; 2818-2822; 35
