Light-emitting element with resonance mode and metal electrode film
The patent US12074410B2 describes a novel light-emitting element that integrates a semiconductor laminate body onto a substrate. This element features a structured arrangement of layers, including first and second cladding layers, an active layer, and a resonance-mode forming layer. The resonance-mode forming layer is characterized by a basic layer and multiple modified refractive index regions, which are distributed in a two-dimensional manner. The design allows for effective light emission, with a specific region designated for laser light output. Additionally, the structure incorporates a metal electrode film that facilitates ohmic contact and light reflection, comprising multiple layers with distinct compositions to optimize performance and solder bonding.
The claims further detail the composition and thickness of the various layers within the metal electrode film, specifying materials such as Au, Ag, Al, Cu, Pt, Ni, and others. The resonance-mode forming layer can also be configured as a photonic crystal, enhancing the light-emitting capabilities of the device. The light-emitting element is designed to be mounted on a submount, with soldering options including Sn solder and lead-free alternatives. This innovative configuration aims to improve the efficiency and functionality of light-emitting devices, potentially impacting various applications in optoelectronics.
