All-optical nonlinear phase noise reduction using an InP-over-SOI PhC nanocavity is experimentally demonstrated for 20-Gbit/s NRZ-QPSK signals. The phase-preserving intensitylimiting function results in an OSNR penalty reduction of 3.5 dB at a BER of 10-3.

We propose a novel cost efficient node architecture for a wavelength division multiplexed packet-switched network based on reflective integrated device. We demonstrate a 16-channel, silicon-on-insulator, reflective monolithic integrated slot-blocker that integrates one arrayed waveguide grating, 16 variable optical attenuators, 16 Bragg grating mirrors and one vertical fiber coupler. Small-form factor...
We demonstrate a 16-channel, silicon-on-insulator, monolithic integrated slot-blocker. This silicon photonic circuit includes two arrayed waveguide gratings, 16 variable optical attenuators and two vertical fiber couplers. We successfully operate it with 56 Gb/s and 80 Gb/s QPSK optical packets.
We report the triple-functionality at 10-Gb/s of an integrated R-EAM-SOA, including modulation, detection and noise-mitigated 2R all-optical signal regeneration. The obtained results demonstrate its high potential for a multi-operation device in colorless WDM access networks.
We demonstrate a 4×170 Gbit/s DWDM/OTDM transmission experiment using only one quantum dash Fabry-Perot mode-locked laser. BER measurements show a penalty of 1dB at BER=10-9 for back-to-back and error floor for BER=10-8 for transmission over 100 km.
A novel WDM-PON delivering 10-Gb/s downstream based on L-band loss-less reflective-amplified-modulator and 2.5-Gb/s upstream based on C-band injection-locked Fabry-Perot laser is experimentally demonstrated for 24 channels over 25-km, using quantum-dash mode-locked laser-based multiple-wavelengths seeding sources.
We report the numerical and experimental studies of a spectrally filtered fiber-based optical limiter at 170 Gbit/s. The device, including less than 1 km-long of highly nonlinear optical fiber and a 3 nm-width filter, exhibits good performance at an average input power of 14.5 dBm. No power penalty has been observed and a strong robustness against optical noise has been demonstrated.
The all-optical regenerator based on self-phase modulation (SPM) and off-centered filtering has attracted much interest thank to its simplicity and efficiency. The regenerator includes a nonlinear fibre and an off- centered filter placed at the output of the fibre. Designing the regenerator consists to find the appropriate set of parameters for the nonlinear fibre and the filter to have an S-shape...
Error-free transmission over 20km of 8-channels for both downstream and upstream in colourless WDM-PON based on injection-locked Fabry-Perot laser is experimentally demonstrated at 2.5Gbit/s, using a single quantum dash mode-locked laser as multi-wavelength seeding source.
Error-free colorless WDM-PON downstream over 25 km for 16 channels with 85 GHz channel spacing is experimentally demonstrated at 2.5 Gbit/s, using an injection-locked Fabry-Perot laser and a quantum dash mode-locked laser as a coherent seeding source.
We report the efficient use of a SPM-based compressor to avoid Brillouin backscattering and intrachannel four-wave mixing in a SPM-based regenerator at 42.6 Gbit/s.
In this letter, we demonstrate the bit-error-rate (BER) performance enhancement of an all-optical clock recovery device at 42.66 Gb/s using a prefiltering operation in front of a self-pulsating semiconductor laser. The prefilter is composed of a simple passive fiber-Bragg-grating-based Fabry-Perot bandpass filter. The assessment is obtained thanks to BER measurement using a data remodulation technique.
We demonstrate performance difference in an 80Gb/s OTDM system employing gain-switched pulses compressed using linearly and nonlinearly chirped fibre gratings. A 3.5 dB power penalty was incurred when the linearly chirped grating was used.
