Far-Field Focus and Dispersionless Anticrossing Bands in Two-Dimensional Photonic Crystals
Far-Field Focus Dispersionless
2008/10/29
We review the simulation work for the far-field focus and dispersionless anticrossing bands in two-dimensional (2D) photonic crystals. In a two-dimensional photonic-crystal-based concave lens, the far...
Coherent combination of laser radiations and fringe contrast ratios on far field patterns
beam combination Fourier-optics dark fringes
2011/5/5
Fourier optics method has been used to study the far field of coherently combined laser beams. And an explicit expression of the far field has been derived for the case when emitters are positioned on...
