VERTICAL-CAVITY SURFACE-EMITTING LASER ARRAY WITH INTEGRATED CAPACITOR

An optical chip may include a vertical-cavity surface-emitting laser (VCSEL) structure. The optical chip may include a capacitor over at least a portion of an active layer of the VCSEL structure that is outside of an active region of the VCSEL structure. The capacitor may include a first metal layer over the portion of the active layer, a dielectric layer on the first metal layer, and a second metal layer on the dielectric layer. The optical chip may include an isolation region between a substrate of the VCSEL and a portion of the capacitor outside of the VCSEL.
