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 tec…

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 isolator…

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 s…

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 f…

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, unrel…
