1. An optoelectronic component comprising,
at least one semiconductor emitter comprising an active region configured to emit electromagnetic radiation of a first wavelength range,
at least one wavelength conversion plate comprising an outcoupling surface and a side surface arranged laterally thereto and aligned transversely thereto, and
a carrier on which the semiconductor emitter and the wavelength conversion plate are arranged, wherein
the outcoupling surface is facing away from the carrier,
the semiconductor emitter is configured to irradiate the wavelength conversion plate with electromagnetic radiation at the side surface, and
the wavelength conversion plate is configured to emit a mixed radiation comprising at least a portion of radiation of the first wavelength range and a converted radiation of a second wavelength range from the outcoupling surface,
wherein the semiconductor emitter comprises an emission cone whose cross-section perpendicular to an axis of the emission cone comprises an elliptical shape, wherein the semiconductor emitter is arranged on the carrier such that the longer ellipse axis is aligned parallel to the main extension direction of the side surface, and
the wavelength conversion plate comprises a plurality of sub regions which are configured to be absorbing or reflecting.
