   TSMC is developing custom detectors for Avicena on their own dime. They almost never do anything like for start-ups. That is why it is a bet on Avicena. They are nurturing this technology because they think it has real potential. See the

   aha! that is true with lasers that are coherent. But not with LEDs. We don't care about modes, polarization, or phase. Also, no worry about feedback into the lasers, so no isolators. LEDs are way easier!

   we use borosilicate fibers that are used for illumination applications. You might have seen a bundle in a microscope light for example. And they are incredibly robust compared to single mode fibers. Note the very tight bend angle in the

   The fiber cables we use are basically 2D arrays of 50um thick fibers that match the LED and detector arrays. We've made connectors and demonstrated very low crosstalk between the fibers. Advantage over VCSELs is much lower power cons

   In datacenters people use optics for longer distances (10m to 2km). Within a rack it is almost always copper. The reason is that for short distances lasers are too expensive, unreliable, and consume too much power. We think microLED base
