We propose and demonstrate a tunable dispersion compensator for 40-Gb/s signals consisting of a waveguide grating router and a deformable mirror.

Today's dense wavelength division multiplexed (DWDM) long haul and metropolitan networks are being upgraded from 10-Gb/s to 40-Gb/s, to support the growing traffic demands.

We monolithically integrate a two-tap optical equalizer (OEQ) with an electro-absorption modulator on InP.

A two-pump parametric architecture is used to demonstrate all-optical packet and bit-level switching at OC-768 data rates.

We experimentally demonstrate polarization-insensitive all-optical clock recovery using a passively mode-locked quantunt-dot Fabry-Perot (QD-FP) semiconductor laser at 40 Gb/s.

We report on the transmission of 40-Gb/s alternate-mark-inversion return-to-zero (RZ-AMI) signals over more than 2600 km (20 x 100 km) of nonzero dispersion fiber at a bit-error ratio of 10(-9).

We report on the transmission of 40-Gbit/s modified duobinary return-to-zero (RZ-MDB) signals over more than 2000 km (20x100 km) at a bit-error ratio of 10 sup -9.

Recently, the differential-phase-shift-keyed signal format has been used to reach record distances in 40-Gb/s long-haul lightwave systems. This paper will review the progress in this area.

We investigate 40-Gbit/s RZ-signal transmission in a transparent optical network equipped with wavelength-selective optical cross connects (WSOXC's).

In this letter, we have developed a tandem electroabsorption modulator with an integrated semiconductor optical amplifier that is capable of both nonreturn-to-zero and return-to-zero (RZ) data tran
