Menggunakan kaedah domain masa perbezaan terhingga, kami menilai prestasi probe gentian medan dekat berbuka dengan struktur tirus dua kali, yang telah mempamerkan, dalam eksperimen baru-baru ini, kecekapan pengumpulan cahaya setempat yang jauh lebih tinggi berbanding dengan tirus tunggal. kuar. Kami menjelaskan bahawa kecekapan pengumpulan yang tinggi ini boleh dikaitkan dengan pemendekan rantau cutoff, dan gandingan yang cekap kepada mod panduan gentian optik. Dengan menghasilkan semula keputusan eksperimen dari segi resolusi spatial dan kecekapan pengumpulan sebagai fungsi diameter apertur, pengiraan kami telah disahkan sah dan berguna untuk reka bentuk probe dalam pelbagai aplikasi.

Abstract: Using the finite-difference time-domain method, we evaluated the performance of apertured near-field fiber probes with a double-tapered structure, which have exhibited, in recent experiments, a much higher collection efficiency of localized light in comparison with single-tapered probes. We clarified that this high collection efficiency could be attributed to the shortening of the cutoff region, and the efficient coupling to the guiding mode of the optical fiber. By reproducing the experimental results in terms of the spatial resolution and the collection efficiency as a function of the aperture diameter, our calculation was confirmed to be valid and useful for the design of probes in a variety of applications.
