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 number of IOs leads to a linear increase in the size of the device.
