On-Chip Optical Communication to Small Footprint Nanowire Neurons
Photonics-based approaches to neuromorphic hardware offer advantages in speed and connectivity but often suffer from large device footprints.[1] Here, we present an ultra-compact artificial neuron built from semiconductor nanowires. A scanning electron micrograph of the nanowire device is presented in Figure 1a, Inside the dashed box, we show the neuron built from three III-V nanowires - two InP pin-doped photodiodes and one InAs-based wire in field-effect transistor (FET) geometry. The two top InP nanowires outside the box are also pin-doped and operated as light emitting diodes (LEDs) to generate on-chip light broadcasting (Figure 1b).
