The silicon photonic modulator neuron constitutes the final piece needed to make photonic neural networks fully integrated on currently available silicon photonic platforms. 中文翻译: 硅光子调制器神经元 最近,人们对神经形态光子学产生了兴趣,该领域有望进入机器智能的关键和未探索的领域。隔离神经元和模拟...
Silicon photonics has shown promise to enable the creation of large scale neural networks. Here, we propose a monolithic silicon opto-electronic resonator spiking neuron. Existing designs of photonic spiking neurons have difficulty scaling due to their dependence on certain nonlinear effects, materials,...
Photonic systems for high-performance information processing have attracted renewed interest. Neuromorphic silicon photonics has the potential to integrate processing functions that vastly exceed the capabilities of electronics. We report first observati
The xi inputs transmit the information to the neuron through the weights Wi which correspond to the strength of the synapses. The summation of all weighted inputs and their transformation via acti- vation function f are associated with the physiological role of the neuron's cell body. The ...
"A network could support N additional neuron connections without adding any physical wires by associating each node with a color of light," Huang explained. "In electronic neuromorphic circuits, in contrast, one more neuron addsNmore connections—a prohibitive situation ifNis large." ...
In addition to device-level optimization and design, we create a new neuromorphic photonics architecture that combines interference with WDM to create a massively scalable, wavelength-diverse integrated photonic linear neuron. This architecture enables dramatic parallelism and physical footprint reduction, ...
In the broadcast-and-weight protocol, shown in Fig. 1(a), each neuron's output is assigned a unique wavelength carrier that is wavelength division multiplexed (WDM) and broadcast. Incoming WDM signals are weighted by reconfigurable, continuous-valued filters called photonic weight banks and ...
By using an eight-beam probe, we show in anaesthetized mice that small groups of single neurons can be independently stimulated to produce multineuron spike patterns at sub-millisecond precision. We also show that a probe integrating co-fabricated electrical recording sites can simultaneously optically...
where 𝑦𝑝𝑖yip is the predicted value of ith output neuron and 𝑦𝑖yi is the ith label of a data sample. Apart from MSE, the loss function can be expressed, e.g., in the form of cross entropy loss function [106]. The loss function 𝐿(𝐲𝐩,𝐲)L(yp,y) is optimize...
The optical stimulation was combined with nearby tungsten electrodes to record the neuron activity. Implantable silicon photonic light delivery probes have also been used for fluorescence imaging [93,94]. For example, Sacher et al. developed implantable probes to generate light-sheets deep in ...
