Abstract: Systems and methods are described herein for an electro-absorption modulator (EAM) device. An example EAM device comprises an optical waveguide comprising a waveguide core configured to facilitate propagation of an optical signal therethrough; a segmented structure comprising diode segments disposed on the waveguide; and a differential electrical transmission line operatively coupled to the diode segments. The electrical transmission line includes a first transmission rail and a second transmission rail, and the electrical transmission line is configured to facilitate propagation of an electrical signal therethrough. The EAM device is configured for operation by a differential radio frequency (RF) source that is configured to supply the electrical signal to the EAM device, and the EAM device is formed on a semi-insulating substrate.

Abstract: Systems and methods are described herein for an electro-absorption modulator (EAM) device. An example EAM device comprises an optical waveguide comprising a waveguide core configured to facilitate propagation and modulation of an optical signal therethrough; a segmented structure comprising diode segments disposed on the waveguide; and an electrical transmission line operatively coupled to the diode segments. The electrical transmission line is configured to facilitate propagation of an electrical signal therethrough. The electrical transmission line includes a first transmission line rail and a second transmission line, where a first subset of diode segments is operatively coupled to the first transmission line rail and a ground rail, and a second subset of diode segments is operatively coupled to the second transmission line and the ground rail. The diode segments from the first subset are disposed alternately with the diode segments from the second subset.
