Photonic wavy structures for angular filtering of light 

Babayiğit, Ceren; Grineviciute , Lina; Gailevicius, Darius; Bor, Emre; Turduev, Mirbek; Purlys, Vytautas; Tolenis, Tomas; Kurt, Hamza; Staliunas, Kestutis (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 ...

Inverse design of integrated photonic structures 

Yılmaz, Yusuf Abdulaziz; Alpkılıç, Ahmet Mesut; Tutgun, Mediha; Yılmaz, Döne; Atalay, İpek Anıl; Yeltik, Aydan; Kurt, Hamza (IEEE Computer Society, 2019)
Designs of photonic devices have been mainly based on intuitive and brute-force approach. However, there has been increasing demand in photonics to obtain high device performance and improved functionalities along with ...

Photonic Crystal Spatial Filters fabricated by Physical Vapour Deposition 

Gailevi?ius, D.; Grinevi?iüte, L.; Babayigit, C.; Bor, E.; Turduev, M.; Purlys, V.; Tolenis, T.; Kurt, Hamza; Staliunas, K (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 

Oner, B.B.; Can, M.G.; Kurt, Hamza (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 

Giden, I.H.; Kurt, Hamza; Turduev, M.; Staliunas, K. (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 

Öner, B.B.; Üstün, K.; Kurt, H.; Okyay, A.K.; Turhan-Sayan, G. (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 

Gayur, E.M.; Öner, B.B.; Kurt, Hamza (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 ...
