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 a propagation of an optical signal therethrough; a segmented traveling wave electrode structure comprising electrode segments disposed on the optical waveguide; and an electrical transmission line operatively coupled to the electrode segments via conducting bridges, wherein the electrical transmission line is configured to facilitate a propagation of an electrical signal therethrough, wherein the electrode segments are configured to overcome bandwidth and extinction ratio constraints of a lumped EAM.
