Abstract
An electro-optic device, such as an optical modulator, comprises: a driver for generating a plurality of identical time-synchronized copies of an input electrical signal, and a photonic integrated circuit, including an optical waveguide structure and a plurality of phase-modulating electro-optical modulator segments. Each one of the modulator segments configured to receive a respective one of the plurality of the copies of the input electrical signal. Instead of incorporating a required phase delay between the copies of the input electrical signal into the driver structure, a multi-layer interconnect substrate is provided that includes a plurality of insulating layers alternating with a plurality of conductive layers. The plurality of conductive layers are configured to include a plurality of delay lines, each one of the plurality of delay lines electrically coupled in between the driver and the photonic integrated circuit configured to transmit a respective one of the plurality of copies of the first input electrical signal.
