Symmetry, stability, and computation of degenerate lasing modes
David Liu, Bo Zhen, Li Ge +6
We present a general method to obtain the stable lasing solutions for the steady-state ab-initio lasing theory (SALT) for the case of a degenerate symmetric laser in two dimensions…
Interaction-induced mode switching in steady-state microlasers
Li Ge, David Liu, Alexander Cerjan +5
We demonstrate that due to strong modal interactions through cross-gain saturation, the onset of a new lasing mode can switch off an existing mode via a negative power slope. In th…
Ab-initio multimode linewidth theory for arbitrary inhomogeneous laser cavities
Adi Pick, Alex Cerjan, David Liu +4
We present a multimode laser-linewidth theory for arbitrary cavity structures and geometries that contains nearly all previously known effects and also finds new nonlinear and mult…
Transformation Inverse Design
David Liu, Lucas H. Gabrielli, Michal Lipson +1
We present a new technique for the design of transformation-optics devices based on large-scale optimization to achieve the optimal effective isotropic dielectric materials within…
