Abstract: An electro-optical modulator. The electro-optical modulator comprising: an input waveguide, configured to guide light into a modulation region of the electro-optical modulator; a plurality of sub-modulators, within the modulation region, each sub-modulator having a transfer function between an applied voltage and an optical phase shift; and an output waveguide, configured to guide light out of the modulation region. The combination of the transfer functions of each sub-modulator is such that a total transfer function between an applied voltage and an optical phase shift of the modulation region is substantially linear over a range of operating voltages.
