We use a new two-dimensional, quasi honeycomb geometry with inter-VCSEL ridge connectors—made nonconducting by selective thermal oxidation—to improve heat dissipation and facilitate a single top surface anode contact. Via on-wafer probing we perform static and dynamic measurements over the wide temperature range of 23 °C to 85 °C and extract, report, and discuss key array figures-of-merit.en530 Physikvertical cavity surface emitting laseroptical interconnectoptical communication19-element vertical cavity surface emitting laser arrays with inter-vertical cavity surface emitting laser ridge connectorsArticle2022-02-032515-7647
