Ultrahigh‐Order Harmonic Mode‐Locked Optoelectronic Oscillator
Laser &Photonics Reviews, EarlyView.This article demonstrates a record‐breaking microwave frequency comb generator using an ultrahigh‐harmonic‐order mode‐locked optoelectronic oscillator. By integrating dual recirculating loops into a low‐coherence system, the researchers achieved a harmonic order of 956 with superior noise suppression.
