Mach - zehnder - modulator and a method for operating a mach - zehnder - modulator

摘要

The present invention relates to an electro - optical mach - zehnder - modulator with a first and second waveguide arm (13, 14), wherein the first and second waveguide arm (13, 14) in each case for guiding at least one first and a second optical mode (m1, m2) is formed, and wherein said modulator (1) is formed, the phase a is in the first and / or second waveguide arm (13, 14) propagating in the first optical mode (m1), as a function of a first modulation signal and the phase a is in the first and / or second waveguide arm (13, 14) propagating in the second optical mode (m2) as a function of a second modulation signal to change.The present invention also relates to a method for operating a mach - zehnder - modulator.n="19"
