This paper presents a simple technique improving the symmetry of tapered fibers and fused directional fiber coupler with a CO2 laser. The uniform heat distribution inside an optical fiber is achieved by using a scanning spot laser beam implementing a galvanometer mirror which applies uniform heat on HZ length of the optical fibers simultaneously. Highly symmetric and low loss tapers and fused couplers are achieved by using an adiabatic criteria.
Keywords: CO2 laser, tapered fiber, fused directional fiber coupler, galvanometer mirror, adiabatic criteria
