  • Publication number: 20240111093
    Abstract: Various embodiments disclosed relate to routing optical signals from silicon photonics, such as a photonic integrated circuit. The present disclosure includes a glass recirculatory layer with waveguides at varying heights to allow re-routing of such optical signals from silicon photonics, such as a photonic integrated circuit. Re-routing of optical signals can be accomplished in the glass recirculatory layer with reduced losses due to reduced intersections of waveguides therein.

  • Publication number: 20220373734
    Abstract: IC chip package with silicon photonic features integrated onto an interposer along with electrical routing redistribution layers. An active side of an IC chip may be electrically coupled to a first side of the interposer through first-level interconnects. The interposer may include a core (e.g., of silicon or glass) with electrical through-vias extending through the core. The redistribution layers may be built up on a second side of the interposer from the through-vias and terminating at interfaces suitable for coupling the package to a host component through second-level interconnects. Silicon photonic features (e.g., of the type in a photonic integrated circuit chip) may be fabricated within a silicon layer of the interposer using high temperature processing, for example of 350° C., or more. The photonic features may be fabricated prior to the fabrication of metallized redistribution layers, which may be subsequently built-up within dielectric material(s) using lower temperature processing.
