The first demonstration of 88 optical switch matrix with low drive voltage digital optical switch elements is reported. A polarization-independent 88 digital optical switch with drive voltage of 40V at 1.3µm wavelength can be realized by assigning proper lengths for switch elements. The average insertion loss of 10dB and polarization independent switching with average crosstalk of -16dB (limited by the middle stage 22 switch) are achieved.
