It is major speculation, but it almost appears that Princeton has patented a "product" using what could have the littlest possibility (IMO) to be Poets "process". If you read Princetons patent granted Jan 2014

"One important aspect of this invention is that an array module as shown in FIG. 8 may entirely be constructed in a wafer level processing in a modular fashion. In one preferred embodiment of the invention, a plurality of array modules each including one or more array chips connected in a desired configuration, are first fabricated monolithically on a single wafer. Referring now to FIG. 1 and FIG. 8 simultaneously, a wafer is first processed to construct at least one reflector and the light emitting region on the entire wafer in an epitaxial growth step. The second reflector may be constructed in one or two steps as per the design requirement for example, if the second reflector is a single type of reflector (FIGS. 1 a and 1 b) or a hybrid reflector (FIG. 1 c). Array chips and interconnection between the array chips in a desired configuration namely, series or parallel connected array chips, are defined using selective metallization or selective etching, to monolithically construct the emission side contact in this particular example. The processed wafer may then be bonded to a transparent carrier substrate that is prepared separately."

Feel free to correct me if im in over my head speculation.
