The optoelectronic oscillator (OEO) has been widely investigated to generate ultra-pure single-frequency microwave signals. In this study, we propose and experimentally demonstrate an active mode-locking optoelectronic oscillator (AML-OEO), which can generate broadband microwave frequency comb (MFC) signa...
A multifunction processor for a broadband signal based on the active mode -locking optoelectronic oscillator (OEO) is proposed and experimentally demonstrated. The central frequency down -conversion and frequency spectrum convolution of the target broadband signal (TBS) are realized by just tuning the ...

Interestingly, the spin degeneracy at points K and K′ is lifted by the broken inversion (time-reversal) symmetry which thus causes a spin splitting of the electronic bands with a strong spin-valley locking. Such an exceptional feature enables access to spins and the valley degree of freedom ...
The optoelectronic oscillator is characterized in that the optical resonant cavity (2) is an active semiconductor resonant cavity. The optoelectronic oscillator has small size, is easy to control stably and can realize frequency tenability. The whole system has integration....
