En utilisant la méthode du domaine temporel aux différences finies, nous avons évalué les performances de sondes à fibre ouverte en champ proche avec une structure à double cône, qui ont montré, lors d'expériences récentes, une efficacité de collecte de lumière localisée beaucoup plus élevée par rapport aux sondes à simple cône. sondes. Nous avons précisé que cette efficacité élevée de collecte pouvait être attribuée au raccourcissement de la région de coupure et au couplage efficace au mode de guidage de la fibre optique. En reproduisant les résultats expérimentaux en termes de résolution spatiale et d'efficacité de collecte en fonction du diamètre d'ouverture, notre calcul s'est avéré valide et utile pour la conception de sondes dans diverses applications.

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.
