Blade condition monitoring systems with fiber-optic sensors attract much attention because they are resistant to lightning strikes, a major issue with increasing blade lengths. However, fiber-optic sensor systems are more complex and more expensive t

A compact polarization-diversity self-coherent receiver with reduced complexity is proposed. Requirements on input polarization tracking is relaxed by a variant CMA equalizer. Ex-periments are performed for 50 and 100 Gb/s PolMUX-NRZ-QPSK signals.

The discrete Fourier Transform (DFT) or its more popular efficient algorithm, the Fast Fourier Transform (FFT) is one of the important mathematical functions in the toolbox of signal processing. To this date its processing speed is limited by the und

An optical vector signal analyzer is presented based on two differential delay interferometer detectors. Orthogonality of inphase and quadrature phase is guaranteed by a monitoring scheme. The time delay can be adjusted to the bit-rate.

A practical scheme to perform the fast Fourier transform in the optical domain is introduced. Optical real-time FFT signal processing is performed at speeds far beyond the limits of electronic digital processing, and with negligible energy consumptio
