I searched for whether any TFLN devices have met this high standard of the Telcordia GR-468 85/85 stress test and I could not find any. With the manufacturing hurdles TFLN offers, if you can't prove the gold standard of reliability than you will mostly lose out to other materials and devices that can.
As KC said yesterday, OpenLight Photonics passed Telcordia guidelines for all active components its PDK. They announced this in March 2025. They mostly rely on indium phosphide to improve their photonic integrated circuits. Smart outfit I would say avoiding TFLN.
When I searched for OpenLight Telcordia testing, I did not mention LWLG but Open AI has already added that LWLG has done so as well in the OpenLight search that I did. LWLG has clearly made a statement that is hard to ignore.
