Abstract
Optical microfibers have been fabricated using a fusion splicer by varying a few control parameters, namely the arc power, fusion time and pulling distance. The geometrical characteristics of the optical microfibers such as length of the transition region and waist, taper angles and cladding diameters are believed to play a role in determining the optical transmission losses. This study revealed the advantage of the one-sided pulling technique to produce small diameter of cladding and core of the optical microfiber namely, 1.43 μm and 0.67 μm respectively with the waist length of 7.35 μm. Strong oscillations of light propagation were observed when the cladding diameter was less than 2μm. The optimum ratio of the taper angle and the transition length are 0.75 and 1.27, respectively with a transmission loss percentage of 16.03%..
