  • Etched facet coupling for flip-chip to photonics chip bonding
    Patent number: 11740407
    Abstract: Disclosed are integrated photonics systems including a coupling strategy to couple light in and out of optoelectronic flip-chips bonded to a photonics chip. The refined tolerances for flip-chip assembly and angled facets defined on both chips at optical couplings improve optical performance.
    Type: Grant

  • Method for fabricating fiducials for passive alignment of opto-electronic devices
    Patent number: 6933536
    Abstract: The present invention relates to a technique for fabricating a mechanical or visual alignment fiducial on a laser die particularly adapted for application with a laser die that is a buried structure edge emitting laser. In fabricating the device, the fiducial and the active mesa are formed in the same photolithography patterning step, using conventional techniques. The active is then buried with regrowth layers. The regrowth layers are subsequently selectively etched to expose the fiducial, leaving the active region protected and buried.
