Talk on Tuesday Dec 13, 2022 at 15:00 Place: Zoom Seminar Title: Integrated optical output layer for a reservoir computer based on frequency multiplexing Speaker: Tigers Jonuzi, VLC Photonics Abstract: <p>Reservoir Computing (RCs) is a brain-inspired computational paradigm based on recurrent neural networks where only output weights are tuned, while internal weights remain untrained. Recently, a photonic RC system that encodes neurons in the lines of a frequency comb was demonstrated. A similar frequency-multiplexing approach was used to implement a single-layer feed-forward neural network. Here, we present the design for an integrated optical output layer for such frequency based photonic neural networks. The all-optical output layer uses wavelength (de)multiplexers and wavelength converters to apply signed weights to neurons encoded in comb lines. The design concept has been split in two integrated circuits comprehending a Silicon Photonic technology for the weighting scheme and an Indium Phosphide platform for the non-linear optical operation. During this talk, simulations and design parameters will be presented and discussed in detail.</p> <p>Zoom link: <a href="https://uibuniversitat.zoom.us/j/87008849910">https://uibuniversitat.zoom.us/j/87008849910</a><br /> Meeting ID: 870 0884 9910</p> Url event:https://ifisc.uib-csic.es/en/events/seminars/integrated-optical-output-layer...
