So called optical microfibers (OMFs) with diameters on the order of one micrometer have attracted much attention during the last years. This results from the optical properties of the OMFs. Due to the small cross section of the OMF about 50% of power guided trough it propagates outside the physical boundary of the OMF. The portion of light guided by the fiber but propagating in the surrounding medium is referred to as the evanescent field. This field can be accessed rather easily for experiments and offers high light intensity because of the strong spacial confinement. This thesis work lays the foundations for the on-demand fabrication of OMFs of any shape and with various optical properties. The scope of this work covers among others the design of an advanced mechanical setup, the corresponding calculations on fabrication of OMFs, and the analysis and verification of the properties of the resulting OMFs.
