Abstract: Described herein are photonic communication platforms and related packages. In one example, a photonic package includes a substrate carrier having a recess formed through the top surface of the substrate carrier. The substrate carrier may be made of a ceramic laminate. A photonic substrate including a plurality of photonic modules is disposed in the recess. The photonic modules may be patterned using a common photomask, and as a result, may share a same layer pattern. A plurality of electronic dies may be positioned on top of respective photonic modules. The photonic modules enable communication among the dies in the optical domain. Power delivery substrates may be used to convey electric power from the substrate carrier to the electronic dies and to the photonic substrate. Power delivery substrates may be implemented, for example, using bridge dies or interposers (e.g., silicon or organic interposers).

Abstract: With a wavelength conversion device based on a nonlinear optical effect, when arrayed waveguides including an intended nonlinear waveguide are fabricated, unwanted slab waveguides are inevitably formed. The slab waveguides can cause an erroneous measurement in the selection of a waveguide having desired characteristics from the arrayed waveguides. The erroneous measurement can lead to redoing steps for fabricating the wavelength conversion device and a decrease in the yield and inhibit the evaluation of the characteristics in selection of the waveguide and the subsequent fabrication of the wavelength conversion device from being efficiently performed. A wavelength conversion device according to the present invention includes a plurality of waveguides formed on a substrate, and a plurality of slab waveguides that are arranged substantially in parallel with and spaced apart from the plurality of waveguides, and each of the slab waveguides has a grating structure that reflects light of a particular wavelength.

Abstract: Configurations for a photonics assembly and the operation thereof are disclosed. The photonics assembly may include multiple photonics dies which may be arranged in an offset vertical stack. The photonics dies may emit light, and in some examples, an optical element may be a detector for monitoring properties such as the wavelength of the light. The photonics dies may be arranged in a stack as a package and the packages may be stacked or arranged side by side or both for space savings. The PIC may include combining and/or collimating optics to receive light from the photonics dies, a mirror to redirect the light, and an aperture structure. The aperture structure may include a region which is at least partially transparent such that light transmits through the transparent region of the aperture structure. The aperture structure may include an at least partially opaque region which may be used for directing and/or controlling the light launch position.
