Abstract
The system includes a generally broadband, low coherence length light source that injects light into a fiber beamsplitter that is used to generate counterpropagating light beams in a Sagnac loop. The loop includes two facing fiber beamsplitters connected together at differing length inner legs, with one of the output legs of the second beamsplitter usually being connected to a in place optical fiber that ends with a phase modulator followed by a mirror. Formatted data is transmitted by impressing relative phase differences between the counterpropagating light beams. Optimum performance depends on appropriate choices for critical lengths in the system.
