Using a unique Ti:LiNbO sub 3 modulator we experimentally identify the value of the modulation chirp parameter that minimizes the transmission power penalty caused by fiber chromatic dispersion.

An improved solder structure with an ultrafine grain size of z similar to 200-500 nm and significantly enhanced mechanical properties has been created by incorporating nanosized, nonreacting, nonco

We report dispersion tolerance enhancement using optical Duobinary detection for optimized 20-70 Gbit/s NRZ Transmission over up to 45-km as a low cost way of dispersion tolerance enhancement in hi

We review some of the recently introduced 10-Gb/s transmitters and techniques that allow wide dispersion tolerances.

Generation of optical SSB signals by a D-EML is extended to its whole bandwidth.

The authors demonstrate a wavelength (de)mux that is dispersion-free and has significantly better figure-of-merit, defined as 1-dB bandwidth over 20-dB bandwidth, over existing devices. 

We have demonstrated a novel multi-channel wavelength demux based on bulk diffraction grating. The demux is in principle dispersion-free and a record FOM of >95% has been achieved.

In this paper, we present a simple analytical model to characterize the effect of fiber chromatic dispersion when using a multisection distributed-Bragg reflector (DBR) semiconductor laser as a mil

Dispersion-managed solitons and their applications in ultra-long-haul transmissions are presented.

We describe a scheme involving the insertion of segments of dispersion compensating fiber, pumped to yield Raman gain, at one or more intermediate points within each 80 km or greater span between a
