A 4×4 nonblocking integrated acousto-optic space switch has been realized, for the first time, in a Y-cut LiNbO3 channel-planar-channel composite waveguide 0.1×1.0×3.0 cm3 in size. Measured performances for nonblocking switching at the optical wavelength of 0.6328 μm include a worst-case crosstalk of −15.6 dB, an average throughput of −16.0 dB, a frequency resolution (frequency increment required for switching between adjacent output ports) of 18.0 MHz, and a reconfiguration time of 0.145 μs.
