    • Design and analysis of all-dielectric subwavelength focusing flat lens 

      Turduev, M.;  Bor, E.;  Kurt, Hamza (Institute Of Physics Publishing, 2017-08)
      In this letter, we numerically designed and experimentally demonstrated a compact photonic structure for the subwavelength focusingof light using all-dielectric absorption-free and nonmagnetic scattering objects distributed ...
    • Differential evolution algorithm based photonic structure design: Numerical and experimental verification of subwavelength ? /5 focusing of light 

      Bor, E.;  Turduev, M.;  Kurt, Hamza (Nature Publishing Group, 2016-08)
      Photonic structure designs based on optimization algorithms provide superior properties compared to those using intuition-basedapproaches. In the present study, we numerically and experimentally demonstrate subwavelength ...
    • Inverse design of next-generation nanophotonic devices 

      Tutgun, M.; Yilmaz, Y.A.; Yeltik, A.; Yilmaz D.; Alpkilic, A.M.; Kurt, Hamza (Institute of Electrical and Electronics Engineers Inc., 2018-07)
      Previous designs of integrated photonic devices mainly included intuitive trial and error approach or optimization methods using parameter search algorithms. The small parameter space and poor investigation of the underlying ...
    • On-chip photonic filter design via objective-first algorithm 

      Tutgun, M.; Alpkilic, A.M.; Yilmaz, Y.A.; Yeltik, A.; Yilmaz, D.; Kurt, Hamza (SPIE, 2018)
      We propose and demonstrate compact on-chip optical filters with ultra-high efficiencies, which are designed via the recently-emerged objective-first inverse design algorithm. The all-dielectric high-pass, low-pass and ...
    • Parametric Study of Wavelength Demultiplexers Designed via Objective-First Algorithm 

      Yilmaz, Yusuf A.; Alpkilic, Ahmet M.; Yeltik, Aydan; Yilmaz, Done; Tutgun, Mediha; Kurt, Hamza (SPIE, 2018-08)
      We demonstrate efficient and compact lxN wavelength-demultiplexing by using objective-first inverse design algorithm. Ultra-high device performances were achieved for the certain designs of 1x2, 1x3, and 1x4 demultiplexers ...
