Abstract
Optical transceivers with more than 50 GBd are
now being deployed, while the use of more than 100 GBd
is currently under investigation. CMOS components, such as
the analog-to-digital converter (ADC) in the receiver path,
can be highly parallelized for higher sampling rates but are
difficult to scale toward higher analog bandwidths. Thus, the
hybrid integration of front-end circuits with the function of a
bandwidth gearbox in other semiconductor technologies is an
interesting research topic. In th
