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.
Optical techniques for bit-level processing of high-speed signals will be reviewed, with emphasis on key device "building blocks" and on demonstrated and potential system applications, particularly
In this paper, we review recent developments in the field of optical regeneration for both ultra long-haul transmission and terrestrial networking applications.
In this letter, we demonstrate all-optical switching of picosecond pulses between the output ports of a microstructure-fiber-based polarization Sagnac interferometer.
This paper presents experimental investigations of the all-optical synchronization of a distributed Bragg reflector (DBR) laser self-pulsating at 40 GHz on various injected bit-rate signals.
All-optical 3R regenerators and regenerative all-optical wavelength converters are envisioned to perform transmission over ultra-long haul distances and to overcome wavelength blocking in TDM netwo
