Enhanced memory capacity of a neuromorphic reservoir computing system based on a VCSEL with double optical feedbacks

In this paper, a neuromorphic reservoir computing(RC) system with enhanced memory capacity(MC) based on a vertical-cavity surface-emitting laser(VCSEL) subject to double optical feedbacks(DOF)is proposed and investigated numerically. The aim of this study is to explore the MC of the proposed system.For the purpose of comparison, the MC of the VCSEL-based RC system with single optic  (本文共12页) 阅读全文>>

Real-time optical spike-timing dependent plasticity in a single VCSEL with dual-polarized pulsed optical injection

We propose and numerically realize an optical spike-timing dependent plasticity(STDP) scheme by using a single vertical-cavity surface-emitting laser(VCSEL). In the scheme, the VCSEL is subjected to an orthogonally-polarized continuous-wave optical injection(OPCWOI) and dual-polarized pulsed optical injections(DPPOI). Based on the widely used spin-flip model, the response spiking dynamics of VCSEL is numerically stud...  (本文共12页) 阅读全文>>

Real-time 850 nm multimode VCSEL to 1 550 nm single mode VCSEL data routing for optical interconnects

Short-reach optical interconnects among massive serves in data centers have attracted extensive research recently. Increasing capacity, cost and power efficiency as well as wavelength switching between data center network nodes are still key challenges for current optical interconnects. In this work, we experimentally demonstrate the real-time intermode optical wavelength switching technique, for high-speed wavelengt...  (本文共5页) 阅读全文>>

A new method for extending rate equation based VCSEL model with multimode spectral characteristic

An accurate VCSEL model is important to evaluate the performance of VCSEL-based high speed short range optical interconnect system. Current VCSEL models show no evidence of the multimode spectral characteristic, which leads to an inaccurate performance estimation of VCSEL-based high speed optical interconnect system especially with large chromatic dispersion. To overcome this problem, we propose a new method to intro...  (本文共8页) 阅读全文>>
