Stable Propagation of Inhibited Spiking Dynamics in Vertical-Cavity Surface-Emitting Lasers for Neuromorphic Photonic Networks

IEEE Access, 2018
We investigate experimentally and theoretically the communication of inhibited spiking dynamics between two interlinked photonic neurons based upon the vertical-cavity surface-emitting lasers (VCSELs).

Reconfigurable Millimeter-Wave Generation via Mutually Injected Spin-VCSELs

Photonics
We propose a novel scheme for generating high-frequency millimeter-wave signals by exploiting period-one (P1) dynamics in a mutual injection configuration of two spin-polarized vertical-cavity surface-emitting lasers (spin-VCSELs).

Performance Improvement of GaN-Based Vertical-Cavity Surface-Emitting Lasers by Using Tapered SiO₂-Buried Structure

IEEE Photonics Journal
In GaN-based vertical-cavity surface-emitting lasers (VCSELs) with insulator-buried structure, the strong index guiding will introduce higher order modes. In this paper, we present a novel GaN-based VCSEL with a tapered SiO2-buried structure by numerical
