Ultra-high-speed optical signal processing of Tbaud data signals

Abstract

We describe methods to generate and optically signal process Tbaud serial optical data signals. We present sub-systems making serial optical Tbit/s systems compatible with standard Ethernet data for data centre applications, and present Tbit/s results using a.o. silicon nanowires.

Cost‐effective all‐semiconductor 4 × 40 Gbit/s transmission in the 1310‐nm wavelength domain

“…Those systems start to be commercially available [3, 4]. Using optical dime domain multiplexing (OTDM), even higher bit rates have been demonstrated [5], but still OTDM transmission is far from being soon commercialized. The other approach to increase the transmission capacity of the optical fiber that gets significantly less attention is based on usage of other than the 1550‐nm transmission window.…”

Ultrahigh-speed and widely tunable wavelength conversion based on cross-gain modulation in a quantum-dot semiconductor optical amplifier

“…In AOWCs, ultrahigh-speed operation is one of the attractive features for future Ethernet applications based on optical time-division multiplexing (OTDM) transmission systems [3]. Indeed, ultrahigh-speed operation of an AOWC has been demonstrated using different nonlinear elements such as highly-nonlinear fibers [4], periodically-poled LiNbO 3 waveguides (PPLNs) [5,6], silicon waveguides [7], chalcogenide glasses [8], and semiconductor optical amplifiers (SOAs) [9−14].…”

Demultiplexing of OTDM-DPSK signals based on a single semiconductor optical amplifier and optical filtering

“…Optical time division multiplexing (OTDM) systems allow generation, transmission, processing, and detection of serial data rates far beyond the speed limit set by electronics [1]. Detection of OTDM signals is usually performed by first extracting the lower speed tributaries from the signal, i.e., demultiplexing from the aggregate rate to the base rate, using high-speed optical switches [2][3][4].…”
