What I thought revealing was that the Arista CEO had never heard before what TFLN or ( thin film) lithium niobate was and had to ask her husband for clarification . She said she wasn’t a chemist and apparently her husband was. Just to show you the material expertise on Arista’s executive level. Fortunately Bertholsheim ( Arista) knew something on polymers. I am sure he now knows more after talking to Lebby. By the way Lebby talked about direct drive eliminating the power hungry power chip. Arista talks about DSP.
