Abstract
Apparatuses, methods, and systems for a modulated laser are disclosed. The modulated laser includes a substrate including a plurality of laser segments, a first laser segment comprising a DC electrode, a second laser segment comprising an AC electrode, an isolation barrier formed between the first laser segment and the second laser segment, and a modulated laser cavity spanning from a rear face to a front face of the modulated laser inclusive of the plurality of laser segments, wherein a primary injection current supporting stimulated emission at a desired optical output power out of the front face of the modulated laser is generated when a DC bias is applied to the DC electrode, and wherein a carrier signal of the modulated laser is modulated when an AC signal is applied to the AC electrode, wherein the AC bias is independent of the DC bias.
