چکیده
Through a computational model, we study the coherence converting capabilities of an array holes in surface plasmon-supporting metal plate, with eye towards creation controlled plasmonic light sources. We evaluate how average and transmission hole depends on parameters array, such as geometry, lattice constant, size. show that location bandgaps resonances can be estimated through simple formula increases are strongly correlated transmission.

Coherence Converting Plasmonic Hole Arrays
Simulations are presented that demonstrate that the global state of spatial coherence of an optical wavefield can be altered on transmission through an array of subwavelength-sized holes in a metal plate that supports surface plasmons. It is found that the state of coherence of the emergent field strongly depends on the separation between the holes and their scattering strength. Our findings su...
متن کاملCoherence matrix of plasmonic beams
We consider monochromatic electromagnetic beams of surface plasmon-polaritons created at interfaces between dielectric media and metals. We theoretically study non-coherent superpositions of elementary surface waves and discuss their spectral degree of polarization, Stokes parameters, and the form of the spectral coherence matrix. We compare the polarization properties of the surface plasmonspo...

متن کاملLight-driven nanoscale plasmonic motors.
When Sir William Crookes developed a four-vaned radiometer, also known as the light-mill, in 1873, it was believed that this device confirmed the existence of linear momentum carried by photons, as predicted by Maxwell's equations. Although Reynolds later proved that the torque on the radiometer was caused by thermal transpiration, researchers continued to search for ways to take advantage of t...
متن کاملArbitrary bending plasmonic light waves.
We demonstrate the generation of self-accelerating surface plasmon beams along arbitrary caustic curvatures. These plasmonic beams are excited by free-space beams through a two-dimensional binary plasmonic phase mask, which provides the missing momentum between the two beams in the direction of propagation and sets the required phase for the plasmonic beam in the transverse direction. We examin...
