(a) The poling setup used for poling a-axis-grown lithium niobate single-crystal
fiber (inset: the fiber’s elliptic cross-section image). (b) One design of the
top interdigital electrode. and inside the inset are
gold electrodes’ width, which are changeable by design in order to adjust the poled domain period
duty cycle.
