Abstract

Photonic devices, packages, and systems with sub-surface compound microlenses are disclosed. An example microlens structure includes a glass core and a microlens stack embedded in the glass core, the stack comprising a plurality of regions stacked a direction of propagation of light that is to be manipulated by the microlens structure, wherein each region is a region of a substantially uniform refractive index that is different from the refractive index of the glass core. Such a stack may be referred to as a “sub-surface compound microlens,” where the term “sub-surface” is indicative of the fact that the stack may be below all surfaces of the glass core (i.e., is embedded in the glass core) and the term “compound” is indicative of the fact that the stack is a compound arrangement of multiple regions (e.g., each region is an individual microlens).
