A novel low-cost photoreceiver integrating an erbium doped waveguide amplifier and a packaged short planar multimode waveguide PIN photodiode demonstrated -21.2 dBm sensitivity at BER 10-10 and PRB

We demonstrate error-free 40 Gb/s packet routing using NRZ-DPSK format through a 64x64 passive optical switch fabric whose 25 GHz passband converts phase into amplitude modulation so that direct de

We demonstrate NRZ and RZ data transmission at 40 Gb/s using a tandem electro-absorption modulator with an integrated semiconductor amplifier (SOA).

We have developed a tandem electro-absorption modulator with an integrated semiconductor optical amplifier that is capable of both NRZ and RZ data transmission at 40 GB/s.

A transmission span of 4 x 100 km followed by an all-optical wavelength converter is cascaded 2500 times.

The implications of the number of laser modes in the spectrum of a filtered clock signal on XPM based retiming is investigated in terms of SBS suppression, spectral broadening and timing jitter.

A circuit-oriented InP/GaAsSb/InP double-heterojunction bipolar transistor (DHBT) technology has been developed, and used to fabricate a 40 Gbit/s full-rate digital circuit (a 40 GHz-clocked D-FF).

A polarisation-independent, push-pull InP Mach-Zehnder modulator for 40 Gbit/s all-optical regeneration has been implemented in a loop transmission scheme.

Single channel 40 Gbit/s pseudo-linear (non-soliton) transmission over 1,000,000 km of TrueWave RS fiber is achieved using all-optical 2R regeneration and in-line synchronous modulation after every

An all-optical wavelength-switch module with 40 Gbit/s capacity is integrated monolithically in InP.
