Latest Patents

One of Chun Lei's latest patents is for a VCSEL semiconductor device. This invention features a vertical surface emitting laser with a mesa structure that has sloping side walls. The design includes a passivation layer with at least two sublayers that partially cover the mesa structure. These sublayers have differing stress components that work to counter each other, minimizing the net stress of the passivation layer. Additionally, the mesa structure incorporates a first stack of mirror layers made from a semiconductor material doped with a first dopant, along with a second stack of mirror layers doped with a second dopant. By controlling the distances of the oxidized portions in these stacks, the internal stress in the mesa structure can be effectively reduced.

Another significant patent is for a photonic device package with an aligned lens cap. This innovative package features a lens cap that is passively aligned, ensuring an unobstructed view of the lens portion. The header, which holds the photonic device, is moved relative to the cap until alignment is achieved, as indicated by a video display system. The cap is secured in place by forming at least one weld point between the cap and the header, followed by a hermetic sealing process to permanently secure the cap.
