Abstract
A first photonic integrated circuit (PIC) comprises a first optical element optically coupled to a first coupling region at an edge of the first PIC. A second PIC is formed in part from a multilayer structure comprising a bottom layer, a top layer comprising a first material with a first index of refraction, and a middle layer comprising a second material with a second lower index of refraction and having a first thickness between the bottom and top layers. The second PIC comprises a plurality of vertical alignment pedestals comprising a portion of the middle layer having the first thickness and attached to at least a portion of the bottom layer, a plurality of thinned regions, and a second optical element optically coupled to a second coupling region at an edge of the second PIC. Two or more of the vertical alignment pedestals are adhered to the first PIC.
