A new method for coupling single-mode fiber to laser diodes with high efficiency and greatly reduced alignment sensitivities is demonstrated.

We simplify phase retrieval receiver by directly using transmission fiber as an dispersive element.

The problem of r.f. transmission lines of > 2 conductors or involving a combination of two lines lying geometrically parallel is treated by the vector potential method.

We investigate robust wireless communication in high-scattering propagation environments using multi-element antenna arrays (MEA's) at both transmit and receive sites.

Companion table and wall telephone sets are described which have been specially designed to eliminate troubles due to excess moisture, dirt, lint, insects and open or high-resistance circuits due t

Simplified Theory of the Multimode Fiber Coupler By K.

In this paper, we study techniques that allow us to relax some constraints imposed by expert knowledge in task specifications of natural language call router design.

The optimality region for beamforming is redefined in terms of two parameters, the signal to noise ratio and the product of the antenna separation and the angular spread in the transmitter.

High speed optical transceiver testing is not only important for transmission performance evaluation but also critical for thermal performance assessment.

Photoresist is an essential material in semiconductor processing and is routinely used as an ion implantation mask.
