Steering Most Probable Escape Paths by Varying Relative Noise Intensities [PDF]

Physical Review Letters, 2014
We demonstrate the possibility to systematically steer the most probable escape paths (MPEPs) by adjusting relative noise intensities in dynamical systems that exhibit noise-induced escape from a metastable point via a saddle point. Using a geometric minimum action approach, an asymptotic theory is developed which is broadly applicable to fast-slow ...

A Compact High-Efficient Equivalent Circuit Model of Multi-Quantum-Well Vertical-Cavity Surface-Emitting Lasers for High-Speed Interconnects

Applied Sciences, 2020
Due to their low power consumption, high modulation speed, and low cost, vertical-cavity surface-emitting lasers (VCSEL) dominate short-reach data communications as the light source. In this paper, we propose a compact equivalent circuit model with noise

Multi-Harmonic Modulation in a Fiber-Optic Gyroscope

Sensors, 2023
Optimizing the bias modulation of a fiber-optic gyroscope is crucial to improving its precision. In this study, we propose and demonstrate the use of multiple harmonics of sinusoidal modulation as an intermediate alternative to the widely used modulation
