Low cost-per-bit high symbol rate transceivers and link capacity upgrade with ultra-wideband (UWB) amplifiers are promising enabling technologies for future cost-efficient optical networks.

We demonstrate a 14.5-Tb/s bi-directional transmission over 2.2 km of OM2 fiber using the selective excitation of four mode groups based on multiplane light conversion technology, wavelength divisi

A new technique for aligning the pulse carver and data modulator in a dual Mach-Zehnder modulator optical transmitter is presented.

We have developed high-speed mid-infrared quantum cascade lasers with direct modulation bandwidth of approximately 7 GHz.

Optical-fiber communication systems that use L E D S as sources and PIN photodiodes as detectors offer the attractive features of reliability, simplicity, and low cost.

Two novelties have been exploited in developing high-speed directly-modulated distributed feedback and distributed Bragg reflector lasers: the use of surface gratings, to enable a single growth and

Due tot he need of operators to protect the high levels of investment in third generation (3G) wireless systems, it seems likely that the path to fourth generation (4G) wireless sytems will be evol

High-speed electrical data transmission through low cost backplanes is a particularly challenging problem.

Driven by increasing bandwidth demand from increasing broadband penetration, video, and other high-bandwidth services, the IEEE 802.3 working group has proposed a new project on higher speed Ethern
