Abstract
A monolithic series-connected laser-diode array is presented, where the array is formed on a non-conductive substrate that includes a plurality of discrete electrically conductive regions. Each laser diode of the array is disposed on a different conductive region such that the laser cavity of each laser diode is optically isolated from its respective conductive region, thereby avoiding optical loss in the laser cavity due to interaction with the highly doped conductive material. Each conductive region is configured to extend past the lateral extent of its respective laser-diode structure. Electrical connection between adjacent laser diodes of the array is made by forming a conductive trace that extends from the top contact of one of the laser diodes to the conductive region on which the other laser diode is disposed.
