Integrated optoelectronic semiconductor component with primary and secondary light sources
A recently granted patent (Publication Number: US11923660B2) discloses an optoelectronic semiconductor component that integrates a primary light source and a secondary light source with exclusively condensed matter between them, eliminating any air gap or free beam path. The primary light source includes a resonator with a semiconductor layer sequence that generates pump laser radiation, while the secondary light source utilizes a pump medium optically pumped by the pump laser radiation. The alignment of the resonator axes and the design of the resonators ensure efficient generation and transmission of laser radiation between the primary and secondary sources.
Furthermore, the patent describes a configuration where multiple primary and secondary light sources are integrated, allowing for independent control of the primary sources and a bijective assignment between the primary and secondary sources. This arrangement is particularly suitable for display devices capable of emitting red, green, and blue light independently in pixels, with the secondary light sources responsible for generating at least the red and green light. The innovative design and integration of these optoelectronic semiconductor components offer potential advancements in display technology and other applications requiring precise control and efficient generation of laser radiation.
