Abstract
Observations of electrically and acoustically induced crosstalk in LiNbO3 waveguide phase modulators at ¿ = 0.633 ¿m are reported. In the tested device, crosstalk attenuation was as low as 23 dB at 700 MHz and 29 dB at 22.83 MHz, which is caused by RF electromagnetic field coupling and by acoustical coupling, respectively, Crosstalk measurements are made as a function of frequency in the electrical and optical domain.
