Optics Express, 2011Co-Authors: Motoharu Matsuura, N Calabretta, Fausto Gomezagis, H.j.s. DorrenAbstract:We present ultrahigh-speed and full C-band tunable Wavelength conversions using cross-gain modulation in a quantum-dot semiconductor optical amplifier (QD-SOA). In this study, we successfully demonstrated error-free 320-Gbit/s operation of an all-optical Wavelength Converter (AOWC) using the QD-SOA for the first time. We also demonstrated full C-band tunable operation of the AOWC in the Wavelength range between 1535 nm and 1565 nm at a bit rate of 160-Gbit/s.

Ultrafast All-Optical Wavelength Routing of Data Packets Utilizing an SOA-Based Wavelength Converter and a Monolithically Integrated Optical Flip–Flop
IEEE Journal of Selected Topics in Quantum Electronics, 2008Co-Authors: Yong Liu, T. De Vries, Johan H.c. Van Zantvoort, J. H. Den Besten, Giok Djan Khoe, Martin T. Hill, Yok Siang Oei, J.h. Den Besten, Johan H. C. van Zantvoort, Tjibbe De Vries, M.k. Smit, Eduward Tangdiongga, Xaveer J.m. Leijtens, A.m.j. Koonen, E. Smalbrugge, H.j.s. DorrenAbstract:We demonstrate all-optical Wavelength routing of 80 Gb/s data packets without using electronic control. The system consists of an optical Wavelength Converter and a monolithically integrated optical flip-flop memory. The integrated optical flip-flop is based on two coupled lasers, exhibiting single-mode operation, having a 35 dB contrast ratio between the states, and switching its state in about 2 ns. The Wavelength Converter is optically controlled by the optical flip-flop. We show that the optical set and reset pulses can force the optical flip-flop to switch its continuous-wave output light between two specific Wavelength positions. The output light feeds the Wavelength Converter, which, in turn, converts the data packet into the flip-flop's output Wavelength, causing the data packet to be routed into a specific port.

error free 320 gb s all optical Wavelength conversion using a single semiconductor optical amplifier
Optical Fiber Communication Conference, 2007Co-Authors: Yong Liu, Giok Djan Khoe, Huug De Waardt, Eduward Tangdiongga, A.m.j. Koonen, Xuewen Shu, Ian Bennion, H.j.s. DorrenAbstract:We demonstrate error-free Wavelength conversion at 320 Gb/s by employing a semiconductor optical amplifier that fully recovers in 56 ps. Error-free operation is achieved without using forward error correction technology. We employ optical filtering to select the blue sideband of the spectrum of the probe light, to utilize fast chirp dynamics introduced by the amplifier, and to overcome the slow gain recovery. This leads to an effective recovery time of less than 1.8 ps for the Wavelength Converter. The Wavelength Converter has a simple configuration and is implemented by using fiber-pigtailed components. The concept allows photonic integration

monolithically integrated 80 gb s awg based all optical Wavelength Converter
IEEE Photonics Technology Letters, 2006Co-Authors: Eduward Tangdiongga, Giok Djan Khoe, M.k. Smit, Huug De Waardt, Y Liu, J Den H Besten, M Van Geemert, T Van Dongen, J J M Binsma, H.j.s. DorrenAbstract:We present a monolithically integrated all-optical Wavelength Converter. The Converter consists of four semiconductor optical amplifiers for four separate inputs and an arrayed-waveguide grating. Error-free Wavelength conversion with reasonable penalties for a 27 -1 pseudorandom binary sequence was shown for a single input 80-Gb/s signal. The device exploits cross-gain/phase modulation in a single amplifier and selects with a filter the blue-chirped spectrum of the new Wavelength signal in order to speed up the device response. This device has a dimension of 1.7times3.5 mm2 and it can be operated to convert simultaneously four 80-Gb/s Wavelength channels

error free all optical Wavelength conversion at 160 gb s using a semiconductor optical amplifier and an optical bandpass filter
Journal of Lightwave Technology, 2006Co-Authors: Yong Liu, Giok Djan Khoe, Huug De Waardt, Eduward Tangdiongga, S Zhang, H.j.s. DorrenAbstract:Error-free and pattern-independent Wavelength conversion at 160 Gb/s is demonstrated. The Wavelength Converter utilizes a semiconductor optical amplifier (SOA) with a recovery time greater than 90 ps and an optical bandpass filter (OBF) placed at the amplifier output. This paper shows that an OBF with a central Wavelength that is blue shifted compared to the central Wavelength of the converted signal shortens the recovery time of the Wavelength Converter to 3 ps. The Wavelength Converter is constructed by using commercially available fiber-pigtailed components. It has a simple configuration and allows photonic integration.

Raman-enhanced regenerative ultrafast all-optical fiber XPM Wavelength Converter
Journal of Lightwave Technology, 2005Co-Authors: Wei Wang, J.e. Bowers, H N Poulsen, Hsu-feng Chou, D J BlumenthalAbstract:The Raman gain enhancement of a regenerative ultrafast all-optical cross-phase modulation (XPM) Wavelength Converter (WC) is quantitatively investigated and experimentally demonstrated to operate error free at 40 and 80 Gb/s. The regenerative nature of the Converter is shown by experimentally demonstrating a negative 2-dB power penalty at 80 Gb/s. It is also shown that the Raman gain greatly enhances the Wavelength conversion efficiency at 80 Gb/s by 21 dB at a Raman pump power of 600 mW using 1 km of highly nonlinear fiber. An analytical theory based on nonlinear phase-shift enhancement of the fiber-effective length is presented and shows the relationship between a nonlinear enhancement and Raman gain as a function of pump power and fiber design parameters. Measured parameters are used in the analytical model, and a good fit between experiment and theory is shown for two different types of fiber: one dispersion-shifted and one highly nonlinear fiber. The ultrafast response time of Raman gain makes this technique applicable to fiber-based ultrafast WCs. In addition, the applicability to other nonlinear fiber Wavelength conversion techniques is discussed.

design and performance of a monolithically integrated widely tunable all optical Wavelength Converter with independent phase control
IEEE Photonics Technology Letters, 2004Co-Authors: Milan L Masanovic, J S Barton, V Lal, J A Summers, E J Skogen, L A Coldren, D J BlumenthalAbstract:We report on a new widely tunable all-optical Wavelength Converter consisting of a sampled-grating distributed Bragg reflector (SGDBR) laser monolithically integrated with a Mach-Zehnder interferometer semiconductor optical amplifier (MZI-SOA)-based Wavelength Converter. The new design incorporates independent phase control of the interferometer and SOAs for amplification of the SGDBR output. For the first time, error-free operation for data rates of up to 10 Gb/s is reported for 35-nm output tuning range. The high-speed operation is enabled by high photon density in the SOA due to large power transfer from the on-board tunable laser and amplifiers. We also report on device sensitivity of -10 dBm at 2.5 Gb/s and -5 dBm at 10 Gb/s, with an average output power of 0 dBm.

monolithically integrated mach zehnder interferometer Wavelength Converter and widely tunable laser in inp
IEEE Photonics Technology Letters, 2003Co-Authors: Milan L Masanovic, J S Barton, V Lal, E J Skogen, L A Coldren, D J BlumenthalAbstract:The first monolithically integrated widely tunable Wavelength Converter, consisting of a sampled-grating distributed-Bragg-reflector laser (SGDBR) and an SOA-based Mach-Zehnder interferometer, is reported. The integration process requires only a single regrowth step. Static extinction ratios (electrical/optical) better than 18 dB and 13 dB, respectively, were measured over a 22-nm Wavelength tuning range. Digital Wavelength conversion at bit rate of 2.5 Gb/s was demonstrated to be error free, with 2.6-dB power penalty.

A penalty of < 3 dB is obtained after Wavelength conversion. Quadrature amplitude modulation (QAM) size and subcarrier number are varied to further evaluate the performance of the Wavelength Converter.

broadband Wavelength Converter based on four wave mixing in a highly nonlinear photonic crystal fiber
Optics Letters, 2005Co-Authors: Ailing Zhang, M S DemokanAbstract:We demonstrate a 10?Gbit?s nonreturn-to-zero Wavelength Converter based on four-wave mixing in a 20?m highly nonlinear photonic crystal fiber. The tunable Wavelength conversion bandwidth (3?dB) is about 100?nm. The conversion efficiency is ?16?dB when the pump power is 22.5?dBm. Phase modulation was not used to suppress the stimulated Brillouin scattering; thus the linewidth of the converted Wavelength remained very narrow. The eye diagrams show that there is no additional noise during Wavelength conversion. The measured power penalty at a 10?9? bit-error-rate level is about 0.7?dB.
