Pulsed Optical Injection Steering in Multistable Semiconductor Laser Arrays under Correlated Noise
Max M. Chumley, Herbert G. Winful
We demonstrate robust programmable state preparation in small Vertical Cavity Surface Emitting Laser (VCSEL) arrays with optical feedback using transient optical injection in the f…
Dynamical System Parameter Path Optimization using Persistent Homology
Max M. Chumley, Firas A. Khasawneh
Nonlinear dynamical systems are complex and typically only simple systems can be analytically studied. In applications, these systems are usually defined with a set of tunable para…
Hall Effect Thruster Forecasting using a Topological Approach for Data Assimilation
Max M. Chumley, Firas A. Khasawneh
Hall Effect Thrusters (HETs) are electric thrusters that eject heavy ionized gas particles from the spacecraft to generate thrust. Although traditionally they were used for station…
Topological Approach for Data Assimilation
Max M. Chumley, Firas A. Khasawneh
Many dynamical systems are difficult or impossible to model using high fidelity physics based models. Consequently, researchers are relying more on data driven models to make predi…
