Abstract
Microwave-optical velocity matching and 50 Omega impedance matching are dif ficult to achieve with LiNbO3 traveling wave modulators. We perform a detai led study (simulations) of the microwave and optical performance characteri stics for modulators using thin layer (few micrometers), X-cut LiNbO3 and f ind significant improvements in velocity and impedance matching together wi th a lower VpiL.
