Rainer,

This is indeed pretty exciting! These patents are the foundation for optical computing or even optical and electrical computing combined. The gates can have various embodiments:

• electrical signals in, electrical signal out (this is what we can do in silicon since decades)
• electrical signals in, optical signal out
• optical signals in, electrical signal out
• optical signals in, optical signal out

Neat! Optical computing won't be something for near-term profits or get rich quick, but this could open up a tremendously broad range of applications and could be a solid foundation for growth over the coming years and perhaps decades.

Seems this is where the $70+ dollar club will see an increased membership.
