We present the design, optimization, and analyses of efficient couplers to construct nano-optical transmission systems involving nanowires. The couplers consist of optimized arrangements of nanocubes and are integrated into critical locations, such as nanowire inputs, corners, and junctions, to improve electromagnetic transmission in accordance with design purposes. Optimization and numerical analyses are performed by employing an efficient simulation environment based on a full-wave solver and genetic algorithms. Using the designed couplers, we obtain various configurations that enable efficient transmission and distribution of input powers to multiple outputs. With their favorable properties, the designed couplers and constructed systems can be further used to build larger nanowire networks.

Design and optimization of nano-optical couplers for controlling transmission between electrically isolated nanowires
Karaova, Gokhan; Tahan, Utku; Atmaz, Tuna; Ergül, Özgür Salih (2019-09-01)
© 2019 IEEE.We present design, optimization, and simulation of effective nano-optical couplers to control power transmission in nanowire networks. The couplers consist of careful arrangements of nanoparticles that are designed in an optimization environment based on genetic algorithms and a full-wave solver. The nanowire segments are electrically isolated from each other, leading to more reconfigurable and adaptable systems. We show that, even in the absence of direct contacts between nanowires, high-perfor...
Computational Design and Analysis of Efficient Couplers for Nano-optical Links
Altinoklu, A.; Ergül, Özgür Salih (2019-01-01)
We present rigorous optimization and design of efficient couplers to improve optical transmission along nanowires. It is well-known that nanowires are excellent tools to transmit electromagnetic power in nano-optical systems, while couplers become inevitable at critical locations, particularly in input/output regions and at corners if nanowires are bended. We use genetic algorithms supported by fast full-wave solutions to efficiently and accurately obtain effective couplers in alternative scenarios. The des...
Computational Design of Optical Couplers for Bended Nanowire Transmission Lines
Tuncyurek, Yunus Emre; Karaosmanoglu, Bariscan; Ergül, Özgür Salih (2017-07-01)
We present computational analysis, optimization, and design of optical couplers that can be useful to improve the transmission along bended nanowires. After demonstrating the deteriorated energy transmission due to sharp bends, which lead to out-of-phase nanowires and diffraction, we use a rigorous simulation environment to design efficient couplers made of spherical particles. For this purpose, an optimization module based on genetic algorithms is combined with the multilevel fast multipole algorithm, lead...
Design and Optimization of Nano-Optical Isolators Based on Irregular Arrangements of Dielectric Rods
Yazar, Şirin; Ergül, Özgür Salih (2022-01-01)
Design and optimization of efficient and compact nano-optical isolators based on irregular arrays of dielectric rods are presented. These designs allow electromagnetic waves to propagate in single direction and prevent them from propagating in the opposite direction. This way, high forward transmission is achieved, while the main source is protected from reflected waves. Effective optimization algorithms are integrated with the multilevel fast multipole algorithm (MLFMA), a fast and accurate full-wave numer...
Design of Compact Nano-Optical Couplers Involving Dielectric Nanorods
Karaosmanoglu, Bariscan; Yazar, Sirin; Ergül, Özgür Salih (2018-06-01)
We present optimization and design of nano-optical couplers involving dielectric nanorods. Using tens of elements, optimal array configurations are found to produce alternative responses that can be digitized. For realistic simulations, the couplers are modeled as three-dimensional structures and analyzed via surface integral equations and the multilevel fast multipole algorithm (MLFMA). Initial results are presented demonstrate the feasibility of compact but effective couplers with desired responses.
