Crosstalk Measurements of Integrated High-Speed Ti:LiNbO sub 3 DELTA beta-Reversal Switching Circuits.
01 January 1989
We report the measurement of directional coupler crosstalk at multi-gigahertz frequencies using an optical sampling method for improved sensitivity. At both 2 and 4 GHz switching frequency, the crosstalk in both switch states of the coupler was
