It's funny to see this show up now. Optical-domain switching was a hot area of research in the early 2000s (e.g. [1]); it largely petered out as it became clear that digital-domain switching was more practical (because it didn't rely on exotic technology, and provided time for hardware to perform routing operations).

- codefeenix 2y agoIs optical digital or analog?
- musicale 2y agoEither/both. A nice feature of lightpath networks is that they are somewhat independent of the signal encoding. Optical computation can also be digital or analog. In this case, the control signal appears to be digital while the switched signal can be anything.
- westurner 2y agoCan [such] optical signals be used for photonic quantum computing; is it only unitary transformations on the photonic signal?
