Abstract

We present a method to build optical tip at the end of a single mode optical fiber. The tip is grown by self-writing process: photopolymerisation by the light coming from the optical fiber. We developed a technique to produce a flat end surface on the tip. The good optical quality of the tip and the output laser beam was demonstrated by the fact that a counterpropagating optical trap could be constructed by using the tips with parameters comparable to regular fiber traps. Due to the small size of the tips the tweezers require a much smaller space than regular fiber traps.
