We implement dispersion-tolerant and time-gating-free alloptical OFDM transmission using a photonic-integrated discrete Fourier transform (DFT) device.

In the framework of synchronous optical packet networks, a cost-effective all-optical synchronizer is an important building block to effectively switch the packets through an optical router.

Lightwave system impairment arising from chromatic dispersion and optical nonlinearity can, in principle, be fully compensated by appropriate use of idlers generated by parametric gain.

This paper presents an all-optical phase conjugation technique based on coherent optical signal processing by cross-phase-modulation in SOA-MZIs.

A novel method to reconstruct the optical phase of fiber laser data pulses allows for generating phase-coded signal formats at record high speed (up to 320 Gb/s).

The photorefractive effect (optically induced index changes) has been extensively studied in electro-optic insulators because of its potential for all optical processing i.e.

We describe the operation of a two-pump parametric optical regenerator. It is shown that higher-order parametric coupling provides optical regeneration with a high extinction ratio.

An all-optical regeneration scheme for DQPSK and QPSK signals using phase-sensitive amplifiers (PSAs) is studied and its effectiveness is investigated through numerical simulations.

: All-optical regeneration, once believed to be the Holy Grail of optical communications for extending reach and mitigating transmission impairments, is now being challenged by the progress in elec

Parametric devices based on four-wave mixing in fibers enable the amplification, frequency conversion and phase conjugation of optical signals.
