Could this be a 'description' of Lightwave's Polymer Modulator Chip ... "V-shaped grooves" ? (ML's presentations)

>>> GlobalFoundries offers one such passive alignment system for the photonic chips it manufactures, wherein PICs are fabricated with V-shaped grooves designed to accommodate incoming and outgoing optical fibers that can then be coupled to the chip using a die attach machine. But Pitkin said that routinely achieving effective adhesive bonding without compromising the alignment or stability of the photonic circuit connections in such systems can pose a notable challenge. Nevertheless, GlobalFoundries is making steady progress with this approach and has incorporated its groove-based passive alignment system into the recently launched GF Fotonix PIC manufacturing platform, which is now being tested by major industry partners such as Cisco Systems and NVIDIA.
