This article presents an optical transmitter front-end based on 2: 1 analog multiplexer
(AMUX) for beyond-1-Tb/s/carrier coherent optical communications systems. An AMUX is …

To enhance sampling rates of CMOS digital-to-analog converters (DACs), analog
multiplexing of several DAC output signals in the time domain provides a solution. In this …

Future generations of optical networks will require optical interfaces that operate beyond 1
Tb/s to keep up with the exploding worldwide Internet data capacity. The data converters …

To cope with the rapid growth of communications traffic, 400-Gb/s/ch digital coherent
systems are being deployed in optical core networks. However, further scaling is required …

A 2: 1 analog multiplexer (AMUX) in SiGe BiCMOS technology with a record sampling rate
for SiGe-technology of 120 GS/s, is presented. The AMUX is intended to double the signal …

Over the last decades, the annual global internet protocol (IP) traffic has been increasing at
an enormous rate and is going to further increase. Overall IP traffic will grow at a compound …

This letter reports on a 108-GHz bandwidth 0.5-InP DHBT analog-multiplexer-driver (AMUX-
driver). To the best of the authors' knowledge, this 2: 1 AMUX-driver shows unprecedented …

We demonstrate, to the best of our knowledge, the highest reported single-and multi-
channel capacities over a field-deployed data center interconnection (DCI) system operating …

Digital-to-analog converters (DACs) for high-speed optical communication systems based
on CMOS technology have bandwidths lower than nowadays electro-optic components. A …

We demonstrate a four-to-one 100-GS/s time interleaver realized in a 55-nm BiCMOS
technology. The interleaver comprises two stages of two-to-one sub-interleavers. Each sub …
