Using surface plasmon polaritons to accelerate the recombination of charge carriers increases the data-generation rate of a light-emitting diode.

Challenges introduced by new transmission standards and the ability to store programs for later viewing are addressed with audio watermarking and fingerprinting.

Quasi-1D systems represent the most desirable design for optoelectronic applications where carrier conductivity is required.

An innovative routing protocol and security algorithm improve the performance of mobile ad hoc networks for military applications.

A symmetric Sagnac interferometric device operates at high speed to avoid data transfer bottlenecks.

The quantum cascade laser's unique properties -- especially its power, tuning range and ability to work pulsed at room temperature -- make it ideal for a variety of gas sensing applications.
