摘要:Two kinds of polarizer coatings were prepared by electron beam evaporation, using HfO2–SiO2 mixture and HfO2 as the high-refractive-index materials, respectively. The HfO2–SiO2 mixture layer was implemented by coevaporat...

摘要:We propose and demonstrate an all‐optical correlator based on modal dispersion in a multimode fiber. Many of the modes can be excited in a large core high numerical aperture step‐index multimode fiber under overfilled launching. The incident optical signal is copied into dif...
