We demonstrate optical performance monitoring using intensity autocorrelations of 10 Gbit/s RZ (return-to-zero) data.

A new technique for monitoring the signal-to-noise (SNR) of a randomly modulated optical data signal is proposed and demonstrated.

In this paper we present a novel technique, based in what we have called Parametric Asynchronous Eye Diagram (PAED).

We describe the use of optical phase conjugation (OPC) to suppress intra-channel nonlinearities limiting pseudo-linear transmission.

We describe the use of optical phase conjugation (OPC) to suppress intrachannel nonlinearities that limit pseudolinear transmission.

We experimentally demonstrate the compensation of intra-channel nonlinear effects in a CSRZ 40Gb/s 32X100 km system using a LiNbO3 optical phase conjugator in a re-entrant, recirculating loop archi

Differential-phase-shift-keying (DPSK) has recently been used to reach record distances in long-haul lightwave communication systems.

We have built a balanced PINFET receiver for homodyne detection of multigigabit-per-second, pilot-carrier PSK optical signals.

Optical pi/2 differential phase-shift keying (pi/2-DPSK) is a modulation technique which encodes the binary information in relative phase shifts of pi/2 and -pi/2 between adjacent optical pulses.
