One main point to take for the analyses is that photons are bosons, so they don't interact between each other, which makes optical switches a pretty hard thing to do. What we do is using interference to make a switch. More specificall

Not even close. Photonics chips and programable photonics are not a way to substitute conventional electronics, but a replacement/complement for some areas of the field where electronics is not efficient.

I'll try an ELI5: When the light propagates in a waveguide as the one used in my circuit, the E and H components of the EM wave are not fully confined to the waveguide, but part of it stays outside the waveguide. If you put two wavegui

The concept of speed that we use in a digital computer does not automatically applies to our optical circuit once we don't work using cycles of a clock. It's not a digital computer, but an operator that realizes a linear operation

I don't see photonics doing the data processing anytime soon. For that our current electronics works just fine. What we do with photonics is to improve areas where the electronics is not efficient. Case and point: interconnections. If

Hi, Photonics ICs are all around. You can find it in many different applications, but mostly in datacom and telecom. A very simple example: anywhere you have a optical fiber you also need a photonic IC to, at least, convert the light into e

The full optical device is no bigger than 1mm x 0.5mm. It's very tiny in total size. The point here is that our current implementation has a limited IO capability (our linear operator has 4 inputs and 4 outputs), but increasing the num

Hi, I'm the author of this paper [15] cited in OP's publication. We are the author of the very first implementation of a fully programmable optical linear circuit in silicon. This is the basic building block to have an optical pro

I really like ST, it is the first text editor that I use for more than 1 year in a row. But 70 Dollars is really expensive in my point of view. I'm not sure if I'll upgrade to version 3 (paying upgrade).
