Abstract
The invention relates to a tapered optical fiber and a method and drawing tower for producing such an optical fiber. The tapered optical fiber comprising a core region that is capable of guiding light along a longitudinal axis of said optical fiber and a cladding region surrounding said core region. The optical fiber comprises a tapered section arranged between a first longitudinal position and a second longitudinal position, said tapered section comprising a first taper section having a first length, L1, over which the optical fiber is tapered down to a taper waist, and a second taper section having a second length, L2, over which said optical fiber is tapered up.
