FIBER-OPTIC DEVICE WITH ONE-DIMENSIONAL ELEMENT FOR NEAR-FIELD OPTICAL SPECTROSCOPY AND MICROSCOPY

摘要

The subject matter (figure 1) is a fiber-optic device (1) with at least one one-dimensional element (3) at the extremity (2) of (1) for near-field optical spectroscopy and microscopy. This device comprises a probe that may be used, preferably, in scanning-probe microscopy and spectroscopy techniques and equipment. The device (figure 1) is suitably dimensioned to carry the light propagated along the fiber to a surface to be analyzed, condensing the light at the fiber output by coupling the light with the one-dimensional element. The subject matter (figure 1) is sufficiently robust for the surface analysis process, and is able to provide high-resolution analysis of structures having dimensions of less than 10 nm.
