Angle-of-Arrival Measurement of a Microwave Signal Using Parallel Optical Delay Detector

A novel parallel optical delay detector is proposed for angle-of-arrival (AOA) measurement of a microwave signal with accuracy monitoring. A theoretical model is built up to analyze the proposed system, including measurement accuracy monitoring. The measurements of AOA are then experimentally investigated with monitored measurement accuracy.

Dispersion in laser-based polymer optical fiber links

We show that factors that have until now been given little attention can have a large impact on the data rate transmission performance of graded-index polymer optical fibers (GIPOF). Our model presents a full description of the dispersion which incorporates all the parameters involved in the determination of the total bandwidth. It is based on analytically evaluating the frequency response of the fiber instead of the direct calculation of the pulse broadening from the moments of the impulse response. We show that the baseband bandwidth is enhanced in GIPOFs mainly due to the large differential mode attenuation (DMA).
