The photonic signal processor consists of a vertical-cavity surface-emitting laser (VCSEL) neuron with dual-polarization optical injection. The reconfigurability is offered by the experimentally ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2025.240220, discusses how phase-change perovskite enables traditional VCSEL to achieve low-threshold, tunable single-mode lasers. As ...

Equipped with Keysight’s next-generation wideband multimode sampling oscilloscope technology and M8199B 256 GSa/s Arbitrary Waveform Generator (AWG), this 200 GBPS multimode VCSEL technology ...

The M8199B AWG drives a 106.25 GBaud PAM4 electrical signal into the Coherent VCSEL, and the PAM4 optical signal output from the VCSEL is measured on wideband multimode scope displaying the eye ...

VCSEL technology performs better in these applications, is more compact and cost-efficient compared to traditional edge-emitting lasers – and the new iPhone X makes good use of the new technology. In ...
