Multi-channel third-harmonic generation via period 3D nonlinear photonic crystals
Results in PhysicsWe report the cascaded third-harmonic generation (THG) via 3D quasi-phase matching (QPM) both theoretically and experimentally. A systematic demonstration of periodic 3D nonlinear photonic crystal (NPC) design for efficient THG is presented.

Channel assisted noise propagation in a two-step cascade
Chaos: An Interdisciplinary Journal of Nonlinear ScienceSignal propagation in biochemical networks is characterized by the inherent randomness in gene expression and fluctuations of the environmental components, commonly known as intrinsic and extrinsic noise, respectively. We present a theoretical framework for noise propagation in a generic two-step cascade (S→X→Y) regarding intrinsic and extrinsic noise.
