Continuously Tunable Large-Dynamic-Range Radio-Frequency Phase Shifter Via a Soliton Self-Frequency-Shifted Source and a Dispersive Fiber

We propose and demonstrate a new approach for achieving continuously tunable true-time-delay radio-frequency phase shifting by using a soliton self-frequency-shifted femtosecond laser source and a highly dispersive fiber. This approach has the advantage of simple configuration, simple operation, and most importantly, the capability to generate large-dynamic-range continuously tunable phase shift.
