16×16 single chip optical switch array in lithium niobate
The design and construction of a lithium niobate 16×16 guided wave switch with a Benes architecture is described. The switch is interfaced to polarisation maintaining optical fibre, has 56 elements, switching voltages ranging between 35 and 60 V and crosstalk suppression of 20 dB at 1.3 μm wavelength.
