Sure, it was the only technology item called out specifically for PDKs by Lebby below.

"We have also completed successful initial testing of our optical grating couplers, which will be part of the Design Tool Kit that will simplify foundry processes and Process Development Kits (PDKs) when integrating our polymer technology with silicon photonics. The introduction of optical grating couplers, integrated with modulators, enable light to be efficiently coupled into and out of the modulator, improving the overall efficacy of an integrated silicon photonics platform. The inclusion of an optical grating coupler in a PDK enables silicon foundry partners to fabricate the modulator and optical grating coupler either simultaneously or in a single fab run.
