  • Patent number: 10998297
    Abstract: A light-emitting assembly that includes multiple light-emitting devices electrically coupled to a substrate via nano-porous metal blocks. The light-emitting assembly may be used as a source array of a near-eye display device. The light-emitting devices may be superluminescent diodes and the nano-porous metal blocks may include nano-porous gold. The nano-porous metal blocks allow thermal and electrical conduction between the light-emitting devices and the substrate. Nano-porous gold allows bonding at a lower temperature than solder and is compressible. Different pressure can be applied to different nano-porous metal blocks to align the optical heights of different light-emitting devices relative to the substrate. After forming nano-porous metal blocks on a substrate, the light-emitting devices are pressed onto the metal blocks to secure and align the light-emitting devices. The alignment process may be carried in an active optical alignment process when the light-emitting devices are powered and emit light.
