Journal ArticleDOI
All-optical space switches with gain and principally ideal extinction ratios
TL;DR: In this paper, three asymmetries in asymmetric Mach-Zehnder interferometer (MZI) configurations with SOA's on their arms are discussed. And the theoretical predictions are verified and found to be in excellent agreement with experiments for a switch with symmetric MZI splitters in a monolithically integrated InP waveguide version.
Journal ArticleDOI
Comparison of all-optical co- and counter-propagating high-speed signal processing in SOA-based Mach-Zehnder interferometers
TL;DR: In this paper, the all-optical signal processing performance of a Mach-Zehnder interferometer (MZI) is investigated and calculated switching windows are used to investigate and understand the physical mechanisms limiting the high speed performance.
Journal ArticleDOI
Ultrafast all-optical demultiplexer based on monolithic Mach–Zehnder interferometer with integrated semiconductor optical amplifiers

TL;DR: In this paper, a monolithically integrated and fully packaged Mach-Zehnder interferometer with semiconductor optical amplifiers (MZI-SOA) is demonstrated as polarisation-independent high-speed demultiplexer for up to 160 Gbit/s optical time division multiplexed (OTDM) data streams.
Proceedings ArticleDOI
All-optical regenerative OTDM add/drop multiplexing at 40 Gbit/s using monolithic InP Mach-Zehnder interferometer
A. Buxens,Anders Clausen,Henrik N. Poulsen,Palle Jeppesen,M. Dulk,E. Gamper,W. Vogt,W. Hunziker,Emilio Gini,H. Melchior +9 more
TL;DR: This work presents a novel method which allows for simultaneous perfect dropping and clearing for 40 Gb/s OTDM signals using a monolithically integrated SOA-MZI and introduces regenerative capabilities at each add-drop node avoiding the cascadability limitation of O TDM add- drop nodes.
Proceedings ArticleDOI
Efficient and robust regenerative all-optical wavelength converter for Cand L-band (80 nm span) and for data rates up to 40 Gbit/s
M. Dulk,St. Fischer,E. Gamper,W. Vogt,W. Hunziker,Emilio Gini,H. Melchior,Henrik N. Poulsen,Anders Clausen,A. Buxens,Palle Jeppesen +10 more
TL;DR: In this article, a monolithically integrated Mach-Zehnder interferometer with semiconductor optical amplifiers (MZI-SOA) was presented for all-optical 2R regenerative 10 Gbit/s wavelength conversion over the full C- and L-band with a negative penalty of about -1 dB.
