Active Delay Stabilization of a 440-km Fiber Link in a Wideband Microwave Delay System
IEEE Photonics Journal（2019）
Abstract
In this paper, a wideband microwave delay system with an equivalent 440-km fiber link is presented. The fiber link propagation delay fluctuation, suffering from temperature variation, is detected incorporating with a reference RF signal. With the help of a variable optical delay line, the wideband microwave frequency output is phase-stabilized. A system figure of merit is investigated in detail. T...
