摘要：
A novel method for passive coupling of light to optical communication links embedded in composite structures has been explored. The use of 45-deg-angled mirrors integrated directly in poly-(methylmethacrylate) fibers as an input node coupling technique was characterized under conditions of varying refractive index. Mirrors were integrated into the fiber through polishing of the endface to a 45-deg angle and then thermal evaporation of Ag metal. To explore angular tolerances and sensitivity to alignment errors, the efficiency of the node was characterized as a function of source position and angle of incidence. Coupling loss as low as -0.39 dB was measured for normal incidence while the input node was immersed in a fluid with refractive index of 1.33. Ray tracing simulations were used to model the coupling of light to fabricated input nodes and showed good agreement with experiments. c 2008 Society of Photo-Optical Instrumentation Engineers.
