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 ...

Surface texturing with multi-objective particle swarm optimization for absorption enhancement in silicon photovoltaics

Atalay, İpek Anıl; Babayiğit, Ceren; Alpkılıç, Ahmet Mesut; Abdulaziz Yılmaz, Yusuf; Kurt, Hamza (IEEE Computer Society, 2019)

Increasing light absorption in ultrathin-film silicon solar cells is important to improve efficiency and reduce costs. In this study, multi-objective particle swarm optimization (MOPSO) is employed to find proper solar ...

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 ...

Parametric study of multi-outputs T-junction spatial mode demultiplexers design with an objective-first algorithm

Alpkılıç, Ahmet M.; Yılmaz, Yusuf A.; Kurt, Hamza (SPIE, 2019)

We design two different compact and low-loss 2D T-junction optical mode demultiplexing by using objective-first inverse design algorithm. These devices are designed for transverse-electric (TE) and transverse magnetic (TM), ...
