Astronomers from the University of Turku in Finland and elsewhere have performed a broadband spectral and timing study of an ...

With the large-scale access of renewable energy to the power system, the interaction of power electronic converters with the weak AC grid may cause broadband oscillation problems. Frequency domain ...

We demonstrate a versatile optoelectronic oscillator (OEO) that can seamlessly switch between single-frequency, dual-frequency, and mode-locking oscillation modes. The OEO operates by shaping the ...
