Abstract :
A compact and low-polarization crosstalk 1/spl times/2 PANDA fiber switch has been developed by precisely aligning the principal axes between the facing fibers. It exhibits an insertion loss of 0.5 dB, a return loss of 42 dB, polarization crosstalk of -30 dB, and a driving power of 9 mW. High-switching reproducibility with a loss change of less than 0.1 dB and a crosstalk change of less than 2 dB were obtained during 10/sup 4/ switching operations.
