Reconfigurable Linear Combination of Phase-and-Amplitude Coded Optical Signals. Paquot, Y., Schröder, J., & Eggleton, B. J. Optics Express, 22(3):2609, January, 2014. doi abstract bibtex We introduce an all-optical arithmetic unit operating a weighted addition and subtraction between multiple phase-and-amplitude coded signals. The scheme corresponds to calculating the field dot-product of frequency channels with a static vector of coefficients. The system is reconfigurable and format transparent. It is based on Fourier-domain processing and multiple simultaneous four-wave mixing processes inside a single nonlinear element. We demonstrate the device with up to three channels at 40 Gb/s and evaluate its efficiency by measuring the bit-error-rate of a distortion compensation operation between two signals.
