Single-mode fiber optical dendritic unit for input correlation learning

EC H2020 ADOPD project 899265 Dissemination actions. We use a single-mode fiber (SMF) optical dendritic unit (ODU) to apply input correlation learning on a system with multiple sensory signals and a reference signal. Each SMF plays the role of a dendritic branch, where plasticity rules apply. At the end of the ODU, a weighted sum of the multiple signals is obtained.

Multi-mode fiber optical dendritic unit for multi-bit header recognition

EC H2020 ADOPD project 899265 Dissemination actions. We use a multi-mode fiber (MMF) optical dendritic unit (ODU) to perform multi-bit header classification at ultrafast speed. The different transient modes that propagate along the MMF have different group velocities and play the role of the dendritic branches. By measuring a single temporal sample, and multiple spatial points of the beam profile of the output pattern of the MMF, we can obtain the classification outcome every 36 picoseconds.
