High order modulation formats constitute the most prominent way for increasing spectral efficiency in transmission systems. Coherent transceivers that support such higher order formats require heavy digital signal processing (DSP), which increases the power consumption of coherent pluggables, well above the intensity …

Photonic neural networks have attracted intense interest during the past decade, with an extensive number of propositions trying to mimic various forms of the established digital models. This field envisages low-power and low-latency, highly parallelized hardware implementations that count on the vast …

We report recurrent optical spectrum slicers as multi-wavelength optical processors in dispersion impaired IM/DD transmission systems with the use of programmable photonics. We demonstrate simultaneous equalization of three$64 ~\text{Gb} / \mathrm{s}$PAM-4 wavelengths after 75 km in the C-band and high tolerance to …

A silicon-photonics recurrent spectral filter is designed, fabricated, and system tested to pro-vide optical pre-processing in a 32-GBd PAM-4 C-band transmission. Performance below FEC is re-ported for up to 100 km reach.

Photonic accelerators have risen as energy efficient, low latency counterparts to computational hungry digital modules for machine learning applications. On the other hand, upscaling integrated photonic circuits to meet the demands of state-of-the-art machine learning schemes such as convolutional layers, remains challenging. …

Abstract: We experimentally investigate a neuromorphic receiver which addresses impairments of a 32 Gbaud self-coherent QPSK transmission and simultaneously generates unclonable responses with an equal error below 10–9 suitable for security in the physical layer.
