Programmable photonics chips based on a versatile structure are crucial for the next generation of advanced systems. In this paper, we designed programmable chip with hexagonal waveguide mesh consisting longitudinally parallel arranged tunable basic units thin-film lithium niobate. We fabricated an effective area 5.2mm×1.5mm, which contains six units, and tested its performance. The extinction ratio both output ports exceeded 15 dB, P π =46mW response time about 32 µs. By programming through PC, it can be configured as multi-channel adjustable optical switch, where each port is greater than dB. This applied to all-optical networks arbitrary path switching.
