Abstract
A frequency diverse distributed Mach-Zehnder Interferometer may include an optical modulator on a chip, with the modulator comprising a plurality of diodes arranged along a waveguide and with each diode driven by two or more drivers. An optical signal may be received in the waveguide, and a first modulating electrical signal may be applied to a first of the plurality of diodes using a first driver and a second modulating electrical signal may be applied to the first of the plurality of diodes using a second driver. The first electrical signal may be different from the second modulating electrical signal. The second electrical signal may have a larger voltage swing than the first electrical signal. The first electrical signal voltage swing may be 0.85 volts and the second electrical signal voltage swing may be 1.5 volts, for example. The first and second electrical signals may have different frequencies.
