Achievement of large spot size and long collimation length using UV curable self-assembled polymer lens on a beam expanding core-less silica fiber
J Kim, M Han, S Chang, JW Lee… - IEEE Photonics …, 2004 - ieeexplore.ieee.org
We report a novel three-segmented fiber-collimator using self-assembled fluorinated
polymer lens and a beam expanding coreless silica fiber of 200-μm diameter spliced to
single-mode optical fiber. Both numerical and experimental analyses are presented for
design, fabrication, and optical characterization of the device. We have obtained a working
distance over 6 mm and a stable spot size over 50 μm in a wide wavelength range of 1.51-
1.59 μm.
