摘要：

Microwave-optical velocity matching and 50 Omega impedance matching are difficult to achieve with LiNbO3 traveling wave modulators. We perform a detailed study (simulations) of the microwave and optical performance characteristics for modulators using thin layer (few micrometers), X-cut LiNbO3 and find significant improvements in velocity and impedance matching together with a lower VpiL.
