Photonic Crystal Spatial Filters fabricated by Physical Vapour Deposition
(Institute of Electrical and Electronics Engineers Inc., 2019-06)
The idea of the angular, or equivalently - spatial, filtering by photonic crystals (PhCs) is based on a selective diffraction of the light propagating through the double-periodic photonic structure. The angular components ...
Partial cloaking by graded index photonic crystals
(SPIE, 2014-04)
Since the first proposal of the idea of optical cloaking, huge research effort has been spent to implement hiding objects. We propose a broad band all-dielectric partial (unidirectional) cloaking device that hides arbitrary ...
Compact rainbow trapping and demultiplexing by photonic crystal waveguides
(Institute of Electrical and Electronics Engineers Inc., 2014)
Graded Index Photonic Crystals (GRIN PhCs) are artificial periodic materials that possess gradually varying effective refractive indices. GRIN profiles can be formed by adjusting the radii or the locations of PhC unit ...
Broadband one way propagation via dielectric waveguides with unequal effective index
(Institute of Electrical and Electronics Engineers Inc., 2014-12)
We present an efficient approach for broad band one way propagation of light by parallel and unequal dielectric waveguides leading different effective phase shifts. Three dimensional numerical simulations show that 30% ...
Enhanced sub-wavelength focusing by tilted and modified graded index medium
(Institute of Electrical and Electronics Engineers Inc., 2014)
The inhomogeneous variation of index distribution as graded index (GRIN) medium focuses light without the curved surfaces. In the current study, we investigate enhanced focusing properties of GRIN medium with tilted front ...
