Compact mass axis alignment device with piezoelements for opticalfibers

A compact mass axis alignment device with piezoelements which can independently align individual optical fibers is proposed. Axis alignment experiments were performed with the fabricated device. The authors describe the construction of the mass axis alignment device. Experimental results of axis alignment with the fabricated device are reported. Splice loss reduction through the use of the proposed device is outlined. The estimated splicing loss that occurs when using the proposed device is 0.063 dB for 1.55-μm DSF
