This paper reviews the work performed under the European ESPRIT project DO_ALL
(Digital OpticAL Logic modules) spanning from advanced devices (semiconductor optical …

The Information Society Technologies-all-optical LAbel SwAp** employing optical logic
Gates in NEtwork nodes (IST-LASAGNE) project aims at designing and implementing the …

Clock recovery is a fundamental operation in digital telecommunications systems, where the
receiver synchronizes itself to the transmitter timing. In optical clock recovery, this operation …

An all-optical address and data separation scheme is presented for short 10-Gb/s packets.
The technique uses a novel packet clock recovery circuit that consists of a Fabry-Perot filter …

In this paper, we review recent advances in ultrafast optical time-domain technology with
emphasis on the use in optical packet switching. In this respect, several key building blocks …

We obtain 40-Gb/s all-optical clock recovery by means of a very simple scheme. We use a
high finesse low-loss Fabry-Pe/spl acute/rot filter and a semiconductor optical amplifier …

We introduce and demonstrate an all-optical clock recovery scheme for return-to-zero
transmission systems based on the buffering property of the temporal Talbot effect. This …

A theoretical model is developed and exploited for characterizing the behavior of an all-
optical circuit that deploys a Fabry-Pérot filter (FPF) and a semiconductor optical amplifier …

In this paper, a technoeconomical study of several (optical) packet-switching node
architectures is described. Therefore, different architectures proposed in IST-WASPNET and …

We demonstrate 1 250 000-km 10-Gb/s return-to-zero transmission over 10 000 stages of in-
line all-optical reamplification, resha**, and retiming (3R) regeneration spaced every 125 …
