We demonstrate a novel fully integrated, silicon-on-insulator, 16-channel polarization diversity fast reflective slot-blocker with nanosecond switching time, integrating more than 65 functional elements. Its suitability for use in reconfigurable metropolitan networks is assessed.
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.

The behavior of a 2R optical regenerator in a link limited by amplified spontaneous emission (ASE) noise and polarization-mode dispersion (PMD) is investigated in detail in this paper. 2R regeneration techniques are well known for combating the accumulation ASE noise in an optical signal, but their behavior in the presence of PMD is mostly unknown. Here, we propose a general method to calculate the...
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.
We report the experimental demonstration of an optical regenerator at 42.6 Gbit/s by using a self-phase-modulation-based pulse compressor and a self-phase-modulation-based regenerator. An improvement of the transmission distance is achieved.
We propose an original study of optical clock recovery characterisation for 3R regeneration. Jitter reduction and corresponding BER measurement are presented at 43 Gb/s using a simple and reliable all optical clock recovery
