Monolithic, electro-optical co-integration for the realization of high end sampler ASICs


Working out the fundamentals of monolithically integrated, optically clocked systems: The jitter of electronically generated clocks and clock distribution structures is a limiting factor for the performance of clocked systems in the GS/s range. Mode-locked lasers generate pulsed light signals which show 1-2 orders of magnitude lower jitter compared to electronic-only approaches. Therefore, the use of a mode-locked laser based clock generation let us expect a strong improvement in the dynamic range of such circuits. The particular goal of this project is the development of monolithically integrated demonstrators proving the jitter improvement when using a mode locked laser as a clock source.
