| Popis: | An efficient way of controlling frequency relies on the strong phase modulation of propagating waves. The authors design a fiber-loop circuit with two phase modulators (PMs) to remarkably enhance phase modulation. Effective gauge potentials can also be introduced by changing the modulation phases of the PMs; varying these potentials shifts the incident frequency spectrum as much as 50 GHz, and yields threefold band expansion. This work is sure to boost applications in spectrum management for optical communication and signal processing. |
