Genetically optimized design of ultra-compact and highly efficient waveguide crossing, optical attenuator and reflector 

Şahin, Umut; Bor, Emre; Kurt, Hamza; Turduev, Mirbek (IEEE Computer Society, 2019)
In this study, we present the design of ultra-compact and highly efficient photonic integrated devices by applying a meta-heuristic approach. Here, we integrated the three-dimensional finite-difference time-domain method ...

Analytical, numerical, and experimental investigation of a Luneburg lens system for directional cloaking 

Babayiğit, Ceren; Evren, Aydın S.; Bor, Emre; Kurt, Hamza; Turduev, Mirbek (American Physical Society, 2019)
In this study, the design of a directional cloaking based on the Luneburg lens system is proposed and its operating principle is experimentally verified. The cloaking concept is analytically investigated via geometrical ...

Transmission enhanced wavelength demultiplexer design based on photonic crystal waveguide with gradually varied width 

Neşeli, Berkay; Bor, Emre; Kurt, Hamza; Turduev, Mirbek (IEEE Computer Society, 2019)
In this study, we propose the design of photonic crystals with linearly tapered waveguide such that waveguide width is gradually varied. Four drop-channels are included to implement wavelength demultiplexing applications. ...

Directional Invisibility of Elliptical Shaped All Dielectric Structure Induced by Evolutionary Optimization Approach 

Babayiğit, C.; Bor, E.; Kurt, Hamza; Staliunas, K.; Turduev, M. (IEEE Computer Society, 2018-09)
This study presents an optimal design of directional optical cloaking device based on evolutionary optimization approach. A cylindrical shaped perfectly electric conductor (PEC) material is selected as an object to be ...

A broadband polarization-insensitive diffractive lens design for subwavelength focusing of light 

Yıldırım, Bumin K.; Bor, Emre; Kurt, Hamza; Turduev, Mirbek (IEEE Computer Society, 2019)
In this study, we propose the metaheuristic design of a polarization-insensitive diffractive lens. The designed lens structure consists of concentric dielectric rings with optimally modulated widths and heights. Here, the ...

Hyperbolic secant graded index photonic crystal flat lens for subwavelength focusing of light 

Evren, Aydın S.; Bor, Emre; Kurt, Hamza; Turduev, Mirbek (IEEE Computer Society, 2019)
In this paper, we propose a graded index (GRIN) medium to obtain subwavelength focusing of light in high and low normalized frequency regimes by using all-dielectric materials. Distributed profile of hyperbolic secant GRIN ...

Photonic crystal rectangular hole based nanobeam cavity refractive index sensor 

Özkaralı, Berk; Bor, Emre; Kurt, Hamza; Turduev, Mirbek (IEEE Computer Society, 2019)
In this study, we propose the design of a one-dimensional photonic crystal rectangular hole based nanobeam cavity structure for refractive index sensing. The designed sensor structure consists of periodic air slots on a ...
