Abstract :
A newly designed low-driving-voltage X-cut lithium niobate optical modulator with a two step backside slot is proposed. This modulator was fabricated with micro-machining technology utilising excimer laser ablation. The modulation bandwidth of this modulator achieves 25 GHz and the driving voltage is 2.8 V at 1 kHz
