实验和理论结果上提出的表面等离子体激元光纤设备，提供选择性激发的双模光纤中的各个模式。采用棱镜耦合探测该器件，实验上获得了对LP/sub 1/1光纤模的良好模式分辨。然而，发现LP/sub 1/1模式鉴别固有地受到双模光纤的场分布特性的限制。应用于固定和可调谐模式抽头或耦合器。<<ETX>>
Experimental and theoretical results are presented on a surface plasmon fiber device that provides selective excitation of individual modes in a dual-mode optical fiber. Using prism coupling to probe this device, good modal discrimination was obtained experimentally for the LP/sub 1/1 fiber mode. The LP/sub 1/1 modal discrimination, however, was found to be inherently limited by the field distribution characteristics of the dual-mode fiber. Applications are to fixed and tunable mode tap or couplers.<<ETX>>
