Self‐Sustained Oscillations in MoS2 Optomechanical Resonators for VHF Optical Radio
Advanced Photonics Research, Volume 7, Issue 6, June 2026.This work demonstrates the use of 2D materials drum resonators to generate and modulate radio‐over‐laser signals. Taking advantage of the self‐sustained oscillations arising in cavity optomechanical systems by a continuous wave visible laser, a radio frequency signal is generated and frequency‐modulated by just changing a DC gate voltage.

A high-frequency electronically tunable quadrature oscillator
IEEE Journal of Solid-State Circuits, 1992 An architecture composed of mutually regenerative oscillators is introduced. It has been used to design a low-noise high-frequency voltage-controlled oscillator (VCO) capable of producing two output signals in quadrature with essentially identical properties. The phase relation between the quadrature outputs is frequency dependent and extremely stable.

Quadrature Based Neural Network Learning of Stochastic Hamiltonian Systems
MathematicsHamiltonian Neural Networks (HNNs) provide structure-preserving learning of Hamiltonian systems. In this paper, we extend HNNs to structure-preserving inversion of stochastic Hamiltonian systems (SHSs) from observational data.
