Exactly! This flexibility will cause a paradigm shift!
I predict that a lot of future "basic technologies" will use this optical interposer technology.
Examples:
- Optical compute chips
- Quantum computing with single photones
- Quantum dot displays
- etc, the list will be long!
Let us remember: When Paul Eisler developed the basic technology for PCB boards in 1936, he had no idea what can be done with it.
