Modern society is definitely more mobile than it was several decades ago. Accompanying the increased mobility is a corresponding craving for greater quantities of information. The increased demand has ...

The advent of all‐optical modulation format conversion techniques has fundamentally reshaped modern optical communications. These techniques enable the direct manipulation of optical signals in their ...

Power-density improvements are an increasingly elusive goal as designers exhaust the easiest or most obvious solutions. One direction that’s now being explored more thoroughly is advanced modulation ...

Optical vector analysis has emerged as a critical tool for characterising optical devices, enabling simultaneous measurement of amplitude and phase responses over wide bandwidths. This technique is ...

Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

One of the biggest challenges facing 3G mobile system service operators is the ability to offer wide area connectivity at 384-kbit/s to 2-Mbit/s data rates, while keeping infrastructure costs to an ...
