... generation and dynamic control of plasmonic Airy beams (PABs). By directly coupling 1D Airy beams from free space to SPPs on a metal surface through a grating coupler, we show that the excited PABs can propagate along parabolic trajectories while maintaining the nondiffracting nature.

Experimental study of Bloch vector analysis in nonlinear, finite
... The Bloch theorem and the Bloch vector are central in many fields of physics, ranging from solid-state physics [1] to optics and photonics [2]. Anywhere the periodic repetition of elements in one, two, or three dimensions (1D, 2D, 3D)—be they atoms, molecules, thin layers of materials, or any generi ...

Modeling second-harmonic generation by use of mode expansion
... Now we study the photonic-crystal cavity device depicted in Fig. 7. In combination with the third-order Kerr nonlinearity this structure gives rise to bistable switching.14 Here we exploit the cavity effects for SHG. The device consists of a resonator mode in the center formed of a larger rod evanes ...
