US 2026/0112860 A1 · LASER BAR CHIP AND METHOD OF MANUFACTURING A LASER BAR CHIP

Abstract

A laser bar chip includes at least a first laser diode, a second laser diode and a third laser diode. The first laser diode, the second laser diode and the third laser diode each include a waveguide structure. The laser bar chip includes a first cathode contact which is electrically connected to the first laser diode, and a second cathode contact which is electrically connected to the second laser diode and the third laser diode. The laser bar chip also includes a first anode contact which is electrically connected to the first laser diode and to the second laser diode.
