Abstract
An edge-emitting semiconductor component, comprising a semiconductor substrate layer and epitaxially on-grown semiconductor layers, is disclosed. According to the invention an active zone of the semiconductor layers is designed to absorb pumped optical radiation of a first wavelength by multi-photon absorption and generate an optical radiation of a second wavelength that is shorter than the first wavelength. A step of multiplying the first wavelength of the pumped optical radiation to a second harmonic using a nonlinear crystal is advantageously made redundant. Furthermore, a system for frequency conversion is disclosed, comprising the semiconductor component, a pump laser diode designed to generate the pumped optical radiation and methods for manufacturing the semiconductor component and operating the system for frequency conversion.
