Beschreibung
Zusammenfassung:	An optical modulator that is adapted to modulate a light signal at very high RF frequencies and provide the modulating RF signal to equipment separate from the modulator is disclosed. The modulator includes a Mach-Zehnder Modulator in which light loses due to the crossing of the RF waveguide conductors and the optical waveguides are reduced. In addition, problems arising from asynchrony between the RF signals and the optical signals are reduced. The modulator also reduces signal losses due to resonances in the modulator. The modulator can be configured to be used in test probes that require a compact configuration that is adapted to designs having multiple test probes that are proximate to each other.
