Each architecture presents trade-offs in bandwidth, footprint, power consumption, linearity, and fabrication tolerance, all aspects that must be considered during the design phase. Optical modulators are key building blocks in modern photonic integrated circuits (PICs), enabling the conversion of electrical signals into high-speed optical data. From telecommunications and datacom to sensing, LiDAR, and quantum technologies, the performance of a photonic system is often. They are fab-ricated on or in planar substrates and it is the properties of this substrate that de-termine the waveguide properties such as electrooptical modulation. An optical modulator is an optical device which is used to modulate a beam of light with a perturbation device.
