Photonic wavy structures for angular filtering of light
(IEEE Computer Society, 2019)
In this study, we propose and experimentally demonstrate spatial filtering of light by the photonic wavy structures designed to be operated in a Bragg regime. The proposed configuration is designed, optimized and analyzed ...
Directionality fields generated by a local Hilbert transform in optics
We propose a new approach of optical field management based on a local Hilbert transform, where the non-Hermitian potentials generating arbitrary vector fields of directionality, p?(r?), with desired shapes and topologies ...
Light Localization and Filtering vertical bar in Three Dimensional Photonic Structures
Three dimensional photonic structures specifically, woodpile photonic crystals, have great potential for manipulating light propagation such as localization and filtering. Efficient harvesting of the energy of the incident ...
Experimental demonstration of broadband perfect invisibility cloak composed of all-dielectric materials
With the development of various recent tools to control electromagnetic wave propagation, such as transformation optics, the long-sought dream of rendering objects invisible has become a matter of practical implementation. ...
Graphene on Silicon-Nitride Photodetector
Even though graphene is a gapless material, it demonstrates strong interband absorption from a broad range of wavelengths between VIS and NIR. Recent photocurrent graphene-based detectors demonstrated strong photoresponse ...
