US 2025/0210941 A1 · STACKED LASER ARRANGEMENT AND METHOD FOR PRODUCING SAME

Abstract

The invention relates to a stacked laser arrangement, including a first laser device having a light exit side and a semiconductor body which forms a resonator and has an active zone and two main sides and side faces arranged substantially perpendicular thereto; wherein the laser device has at least one contact region on a first of the two main sides. Moreover, a first spacer having a first contact main side and a contact side face is provided, with the contact main side having at least one contact line which leads from a contact region to a connection area on or adjacent to the contact side face. With its first main side facing the first contact main side, the first laser device is fastened to the first spacer such that the at least one contact region is electrically connected to the contact region of the first contact main side, and the side faces of the first laser device are spaced apart from the contact side face.

Dependent claims

A stacked laser arrangement, comprising:

a first laser device comprising a light-emitting side and a semiconductor body forming a resonator and with an active zone and with two main sides and side surfaces arranged substantially perpendicularly thereto;
the laser device having at least one contact region on a first of the two main sides;
and
a first spacer comprising a first contact main side and a contact side surface;
the contact main side comprising at least one contact line leading from a contact area to a terminal surface on or adjacent to the contact side surface;
wherein
the first laser device is attached to the first spacer with the first main side facing the first contact main side, so that the at least one contact area is electrically connected to the contact area of the first contact main side and the side surfaces of the first laser device are spaced apart from the contact side surface, and
wherein a length of the first spacer is less than a length of the first laser device and the first spacer is recessed with respect to the light emitting side.
