Abstract
Optical packet switching has received considerable attention over the last few years. In this paper we discus how optical signal processing can play a role in photonic packet routing. Two examples are given. Firstly we discuss ultrafast wavelength switching at 160 Gbit/s in a single semiconductor optical amplifier. Secondly, an integrated photonic flip-flop is discussed. Finally a discussion is given about potential opportunities and limitations of optics in packet switched nodes.

A fast low-power optical memory based on coupled micro-ring lasers.

TL;DR: Simulations show that the ring lasers with extremely small size and low operating power presented here have the potential for much smaller dimensions and switching times, and large numbers of such memory elements can be densely integrated and interconnected on a photonic integrated circuit.

Subpicosecond gain dynamics in InGaAsP optical amplifiers: Experiment and theory

J. Mark, +2 more
TL;DR: In this paper, pump-probe measurements on bulk InGaAsP optical amplifiers are compared with numerical calculations based on simplified density matrix equations, and the gain dynamics is well described by the combined effect of carrier heating, spectral hole burning, and two-photon absorption.
