Optimizing a modulator driver for linear and high-speed operation, while simultaneously achieving a high output voltage swing is very challenging. This paper investigates the design of a highlylinear, high-bandwidth yet power-efficient Mach-Zehnder m

This paper presents a brief study of the two most commonly used topologies - segmented and traveling-wave - for realizing monolithically integrated electro-optical transmitters consisting of Si-photonics Mach-Zehnder modulators and their electrical d

This paper presents a modulator driver realized as a breakdown voltage doubler which can provide a high output swing of 7.6 Vpp,diff for load impedances as low as 30 Ω, thus overcoming the limitation imposed by the collector-emitter breakdown voltag

This paper discusses the technology development for integration of parallel optical interconnects on board-level, including the active and passive optical components as well as the electrical integrated circuitry. The inter-chip link is based on plan

To accommodate the growing demand on higher speeds, low latencies and low energy consumption, the interconnections within and between data centers are supposed to be implemented as optical fiber and waveguide interconnects in future. Optical fiber in

In future, computing platforms will invoke massive parallelism by using a huge number of processing elements. These elements need broadband interconnects to communicate with each other. Following More-than-Moore concepts, soon large numbers of proces

Large scale data centers (DC) and high performance computing (HPC) systems require more and more computing power at higher energy efficiency. They are already consuming megawatts of power, and a linear extrapolation of trends reveals that they may ev

The design of an analog frontend including a receiver amplifier (RX) and laser diode driver (LDD) for optical communication system is described. The RX consists of a transimpedance amplifier, a limiting amplifier, and an output buffer (BUF). An offse

This paper discusses the challenges and the trade-offs in the design of laser drivers for very-short distance optical communications. A prototype integrated circuit is designed and fabricated in 28 nm super-low-power CMOS technology. The power consum

Existing optical networks are driven by dynamic user and application demands but operate statically at their maximum performance. Thus, optical links do not offer much adaptability and are not very energy-effcient. In this paper a novel approach of i
