Abstract
A photonic integrated circuit (PIC) die are provided. The PIC die includes a set of optical connect grooves including a first groove aligning a core of a first optical fiber positioned with a first optical component in a first layer at a first vertical depth in a plurality of layers of a body of the die, and a second groove aligning a core of a second optical fiber positioned therein with a second optical component in a second, different layer at a second different vertical depth in the plurality of layers. The grooves may also have end faces at different lateral depths from an edge of the body of the PIC die. Any number of the first and second grooves can be used to communicate an optical signal to any number of layers at different vertical and/or lateral depths within the body of the PIC die.
