Active damping control of multi-scale oscillations in new energy grid connection considering wideband negative resistance characteristics

Results in Engineering
Due to the stochasticity and complexity of renewable energy grid-connected systems, conventional control methods are limited to single-frequency-point regulation and lack broadband adaptability, making it difficult to effectively suppress wideband ...

Cascaded half-harmonic generation of femtosecond frequency combs in mid-IR [PDF]

, 2015
For the growing demand of frequency combs in mid-infrared (mid-IR), known as the "molecular fingerprint" region of the spectrum [1], down conversion of near-IR frequency combs through half- harmonic generation offers numerous benefits including high ...

Ultrafast broadband optical spectroscopy for quantifying subpicometric coherent atomic displacements in WTe_{2}

Physical Review Research, 2019
Here we show how time-resolved broadband optical spectroscopy can be used to quantify, with femtometer resolution, the oscillation amplitudes of coherent phonons through a displacive model without free tuning parameters, except an overall scaling factor ...

Periodic spiking pulse formation in broadband nonlinear optoelectronic oscillator

Optics Express
An approach to generating periodic spiking pulses in a broadband opto-electronic oscillator (OEO) without external injection is proposed and demonstrated. Through biasing the electro-optic Mach-Zehnder modulator (MZM) in the OEO cavity at its nonlinear working point, spiking pulses are excited by the self-generated chaos under the combined action of ...
