Article: Phase-Incoherent DQPSK Wavelength Conversion Using a Photonic Integrated Circuit
[show abstract] [hide abstract]
ABSTRACT: We investigate the performance of a large-scale, silica-on-silicon photonic integrated circuit for multiformat signal processing, and we experimentally demonstrate wavelength-conversion of (differential) quadrature phase-shift keying [(D)QPSK] signals. The circuit exploits phase-incoherent techniques to decode the input signal and to phase remodulate two phase-shift-keying components before combining them in a common QPSK output stream. Error-free wavelength conversion with 4-dB power penalty is reported at 44 Gb/s.IEEE Photonics Technology Letters 12/2011; · 2.19 Impact Factor -
Article: Multi-format all-optical processing based on a large-scale, hybridly integrated photonic circuit.
[show abstract] [hide abstract]
ABSTRACT: We investigate through numerical studies and experiments the performance of a large scale, silica-on-silicon photonic integrated circuit for multi-format regeneration and wavelength-conversion. The circuit encompasses a monolithically integrated array of four SOAs inside two parallel Mach-Zehnder structures, four delay interferometers and a large number of silica waveguides and couplers. Exploiting phase-incoherent techniques, the circuit is capable of processing OOK signals at variable bit rates, DPSK signals at 22 or 44 Gb/s and DQPSK signals at 44 Gbaud. Simulation studies reveal the wavelength-conversion potential of the circuit with enhanced regenerative capabilities for OOK and DPSK modulation formats and acceptable quality degradation for DQPSK format. Regeneration of 22 Gb/s OOK signals with amplified spontaneous emission (ASE) noise and DPSK data signals degraded with amplitude, phase and ASE noise is experimentally validated demonstrating a power penalty improvement up to 1.5 dB.Optics Express 06/2011; 19(12):11479-89. · 3.59 Impact Factor -

[show abstract] [hide abstract]
ABSTRACT: Demonstration of all-optical packet switching at 160 Gb/s over a total of 110-km field installed optical fiber link is reported. The packet switch architecture is based solely on photonic circuits: an optical filter as label processor, an all-optical flip-flop as memory element and an ultrafast wavelength converter as router. Both flip-flop and wavelength converter uses semiconductor optical amplifiers which allows for photonic integration. The switch operates at low power levels and shows potential scalability.

Article: 160-Gb/s All-Optical Packet-Switching With In-Band Filter-Based Label Extraction and a Hybrid-Integrated Optical Flip-Flop
[show abstract] [hide abstract]
ABSTRACT: An in-band labeling scheme with filter-based label extraction is employed for very high-speed optical packet-switching. The scheme shows a potentially high scalability, up to 25 labels in a 5-nm bandwidth packet using commercial arrayed waveguide gratings as the label processor. Switching is demonstrated using packets with two different 9-ns labels, 6.4- and 4.6-ns guard times, and 56.8-ns payload at 160 Gb/s. The system uses a tunable optical filter as the label extractor, a hybrid integrated optical flip-flop, and a high-speed semiconductor-optical-amplifier-based wavelength converter. Error-free operation is achieved with acceptable error penalties.IEEE Photonics Technology Letters 08/2007; · 2.19 Impact Factor -
Article: Optical signal processing using integrated multi-element SOA-MZI switch arrays for packet switching
[show abstract] [hide abstract]
ABSTRACT: The use of discrete but interconnected SOA-MZI switches for performing logical and highly functional processing tasks, demonstrating the multi-functional potential of the photonic switching elements is discussed. An all-optical 3R burst-mode receiver consisting of four SOA-MZI switches and operating error-free with 40-Gb/s optical bursts, proving that interconnection of multiple switching units can lead to the realisation of key network node functionalities offering increased intelligence at the physical layer is presented. In order to allow for easier interconnectivity between the SOA-MZI switches and to provide compactness and cost effectiveness to the developed subsystems, the integration of multiple switches into the same platform is proposed. To this end, the implementation of the first integrated quadruple SOA-MZI switch array is reported, increasing the integration density level and reducing packaging and pigtailing costs. Finally, possible applications of integrated multiple switch arrays are discussed, indicating their suitability for producing compact circuits performing common processing tasks in a multi-wavelength environment, as well as their potential to lead to the development of an all-optical high-speed packet switched node by implementing critical packet switching functionalities in a compact and efficient way.IET Optoelectronics 07/2007; · 1.03 Impact Factor
