Abstract

A laser light source having a ridge waveguide structure includes a semi-conductor layer sequence having a number of functional layers and an active region that is suitable for generating laser light during operation. At least one of the functional layers is designed as a ridge of the ridge waveguide structure. The semiconductor layer sequence has a mode filter structure that is formed as part of the ridge and/or along a main extension plane of the functional layers next to the ridge and/or perpendicular to the main extension plane of the functional layers below the ridge.
