Exploiting spacetime symmetry in dissipative nonlinear multimode amplifiers for output control
Chun-Wei Chen, Kabish Wisal, Mathias Fink +2
Time-reversal symmetry enables shaping input waves to control output waves in many linear and nonlinear systems; however energy dissipation violates such symmetry. We consider a sa…
Theory of Transverse Mode Instability in Fiber Amplifiers with Multimode Excitations
Kabish Wisal, Chun-Wei Chen, Hui Cao +1
Transverse Mode Instability (TMI) which results from dynamic nonlinear thermo-optical scattering is the primary limitation to power scaling in high-power fiber lasers and amplifier…
Mitigating stimulated Brillouin scattering in multimode fibers with focused output via wavefront shaping

Topological state transfer in Kresling origami
Yasuhiro Miyazawa, Chun-Wei Chen, Rajesh Chaunsali +4
Topological mechanical metamaterials have been widely explored for their boundary states, which can be robustly isolated or transported in a controlled manner. However, such system…
Subwavelength and directional control of flexural waves in zone-folding induced topological plates
Rajesh Chaunsali, Chun-Wei Chen, Jinkyu Yang
Inspired by the quantum spin Hall effect shown by topological insulators, we propose a plate structure that can be used to demonstrate the pseudo-spin Hall effect for flexural wave…
