TLDR
The ability to manufacture a reference tapered fiber lens with high symmetry at sub-wavelength scale with a wide range of geometry control is demonstrated, either for the length from several hundred nanometers to several hundred microns, or for the curvature radius on the endface of a single mode fiber.Abstract:
In numerous applications of optical scanning microscopy, a reference tapered fiber lens with high symmetry at sub-wavelength scale remains a challenge. Here, we demonstrate the ability to manufacture it with a wide range of geometry control, either for the length from several hundred nanometers to several hundred microns, or for the curvature radius from several tens of nanometers to several microns on the endface of a single mode fiber. On this basis, a scanning optical microscope has been developed, which allows for fast characterization of various sub-wavelength tapered fiber lenses. Focal position and depth of microlenses with different geometries have been determined to be ranged from several hundreds of nanometers to several microns. FDTD calculations are consistent with experimental results.read more
