3D Printing Technology for Tapered Optical Fiber Protection With Gas Sensing Possibilities
Photonic Sensors, 2020 We present a new procedure for protecting micro-optical fibers (tapered fibers) by using the 3-dimension (3D) printing technology. A standard single-mode optical fiber was tapered down to the diameter of 1 µm and embedded in a polymeric matrix obtained ...

A fiber-diffraction interferometer using a coherent fiber optic taper [PDF]
Measurement Science and Technology, 2010 We present a fiber-diffraction interferometer using a coherent fiber optic taper for optical testing in an uncontrolled environment. We use a coherent fiber optic taper and a single-mode fiber having thermally-expanded core. Part of the measurement wave coming from a test target is condensed through a fiber optic taper and spatially filtered from a ...

Tapered optical fiber for Micro-Newton force sensor [PDF]
EPJ Web of Conferences, 2020 We used Brillouin scattering in silica nanofiber to demonstrate a microNewton force sensor having weak optical losses and using only one access of the nanofiber. The measurements are in good agreement with the theoretical model.

On-chip optical fiber-to-nanophotonic waveguide adiabatic coupler [PDF]
AIP AdvancesWe report a simple design of an on-chip optical fiber-to-nanophotonic waveguide adiabatic coupler. An inverse-tapered waveguide can be fabricated on an etched oxide layer to achieve index-crossing with a tapered optical fiber without severe light leakage
