1) That is the correct image from the Google shout out. Zwickel was the reference. The date was 2020 but I think it was just a continuation of the 2018 paper you posted. It’s a slot modulator structure so of course LWLGs pictures and these pictures are going to look the same.
2) LWLG owns the IP for the technology in the 5k hour paper. You gotta peel the onion back on these types of stats to see what may or may not be significant. There’s material only tests, tests on devices, tests on packaged devices. LWLG’s data today is packaged devices that are quasi-hermetically sealed using the ALD and do not require a gold box package for that hermetic seal. Leaps and bounds ahead of that paper.
3) 100% poling efficiency there isn’t what you think it means. There, it means the material r33 stayed the same when they put it into a device. Generally there’s a reduction in r33 “in-device”.
