Therefore, in this article, an HEF incorporating active Y-capacitor (AY-HEF) is proposed for effectively mitigating common-mode (CM) noise in the wide frequency band. The proposed AY-HEF can ...

Abstract: Narrow linewidth and stabilized light injection is employed to reduce the phase noise and stabilize the frequencies of individual teeth of an active mode-locked laser diode (ML-LD) which is ...
