Mk. Chin, SIMPLE ELECTRICAL BIASING FOR MINIMIZING THE NONLINEARITIES OF QUANTUM-WELL MACH-ZEHNDER MODULATORS, Applied optics, 33(9), 1994, pp. 1732-1734
The quadratic nature of the electro-optic effect in semiconductor Mach
-Zehnder modulators based on the quantum-confined Stark effect allows
simple electrical biasing to eliminate either the second-order or the
third-order distortions in the optical output, improving the device li
nearity for single-octave bandwidth multicarrier analog modulation app
lications.
