- Utilization of two polarization modulators for signal control.
- Implementation of a reflecting switch architecture for data stream exchange.
Main Results:
- The switch provides a through path when one input is active.
- It enables a full exchange of incoming data streams when both inputs transmit.
- The switch can detect backpropagating beams, split them, and route them to inputs.
Conclusions:
