概要

論文の詳細を見る
The first demonstration of 8×8 optical switch matrix with low drive voltage digital optical switch elements is reported. A polarization-indeependent 8×8 degital optical switch with drive voltage of ±40 V at 1.3 μm wavelength can be realized by assigning proper lengths for switch elements. The average insertion loss of 10 dB and polarization independent switching with average crosstalk of -16 dB (limited by the middle stage 2×2 switch) are achieved.
