We present an all-optical regeneration technique based on spectral filtering of self-similar parabolic pulses (similaritons). In particular, we demonstrate numerically and experimentally that ghost pulses, which occur in the zero bit slots of telecommunication pulse trains, can be effectively suppressed. These results are obtained with a 40 Gbit/s pulse train.

A rigorous full-vectorial finite element analysis has been carried out to study a composite plasmonic horizontal slot waveguide and its application in DNA hybridization and surface sensing at the telecommunication wavelength λ = 1550 nm. OCIS codes: (230.7370) Waveguides; (240.6680) Surface plasmons; (130.6010) Sensors; (280.4788) Optical sensing and sensors

We consider the counterpropagating interaction of a signal and a pump beam in a spun fiber and in a randomly birefringent fiber, the latter being relevant to optical telecommunication systems. On the basis of a geometrical analysis of the Hamiltonian singularities of the system, we provide a complete understanding of the phenomenon of polarization attraction in these two systems, which allows t...

We demonstrate efficient spectral compression of picosecond pulses in an all-fiber configuration at telecommunication wavelengths. Thanks to parabolic pulse shaping, a spectral compression by a factor 12 is achieved with an enhanced Strehl ratio. OCIS codes: 190.4370 (nonlinear optics, fibers), 320.5540 (pulse shaping), 070.4340 (optical signal processing)

Measurements of birefringence correlation length performed on long single-mode telecommunication fibers are reported. The proposed technique relies on the statistical properties of the backscattered-field polarization, which was measured by means of a polarization-sensitive optical time-domain reflectometer. Experimental results are reported that show good agreement with the underlying theory b...

A soft decoding technique is discussed in this paper to improve the performance of long-distance optical networks (LDOTNs). LDOTNs are affected by phase noise and nonlinearities generated inside fiber. The investigations proposed LDOTN were carried out dual-polarization 16-quadrature amplitude modulation (DP-16QAM), DP-64QAM over single-mode fiber (SMF) digital signal processing (DSP) methodolo...

We demonstrate two-dimensional photonic crystal cavities operating at telecommunication wavelengths in a single-crystal diamond membrane. use high-optical-quality and thin (~ 300 nm) membrane, supported by polycrystalline frame, to realize fully suspended with high theoretical quality factor of ~ $8\times10^6$ relatively small mode volume ~2$({\lambda}/n)^3$. The are fabricated the membrane usi...

Dispersion is widely existed in the optical fiber. The reason is various, such as material dispersion, waveguide dispersion, mode dispersion, and so on. It will lead to the signal waveform distortion and pulse broadening and then limit the transmission capacity and bandwidth in the optical fiber. With the rapid development, transmission rate can reach even hundreds of Gb/s, and it may lead to m...
