We demonstrate a new spectrographic method for the simultaneous temporal characterization of optical pulses and modulators.

This memorandum contains the text of an invited lecture to be given at the Winter School on Glasses and Ceramics from Gels which will be held at the University of Sao Paolo in Sao Carlos, Brazil,

The analysis of the multiple-antenna capacity in the high-SNR regime has hitherto focused on the high-SNR slope (or maximum multiplexing gain), which quantifies the multiplicative increase as a fun

As 100-Gb/s coherent systems based on polarization-division multiplexed quadrature phase shift keying (PDM-QPSK), with aggregate wavelength-division multiplexed (WDM) capacities close to 10 Tb/s, a

Perfluorinated graded-index polymer optical fibers (GI-POF's) have been developed that offer low losses (50 dB/km) and high bandwidth (>0.3 GHz.km) at data communication wavelengths (0.85 and 1.

High-speed 1.3-microns GaInAsP p-substrate buried crescent lasers were made with an MOVPE-grown semi-insulating Fe/Ti-doped InP current blocking layer.

A 2x2 array of individually driven MQW modulators has been fabricated.

we propose and demonstrate all-optical method for generating advanced modulation formats with high spectral efficiency.

SiGe-based high-speed ADCs are promising for emerging higher frequency band applications such as coherent optical systems or millimeter-wave radios because of the inherent advantages of high-speed,

Over the past 50 years, digital communication technologies of various sorts have transformed our society into a true communication and information so- ciety.
