We introduce a concept of light trapping on the nanoscale via pinning optical vortices to optimally-designed nanostructures, reveal this mechanism behind known focusing phenomena, and offer new approaches to design nanophotonic platforms and/or coupling schemes. © 2013 Optical Society of America.

Integrated optical modulators with zero index metamaterials based on photonic crystal slab waveguides
Yildirim, Mustafa; GÖVDELİ, ALPEREN; Kocaman, Serdar (2019-01-01)
A novel integrated optical modulator design is presented using zero index metamaterial-based Mach-Zehnder Interferometer with photonic crystal phase shifters. The phase modulation relies on the shift between the photonic bandgaps having non-zero and zero effective refractive indices. A small change in the bulk index results in an effective index change between the arms of the MZI due to the disturbance of the band structure. Thus, such a structure provides a new approach for phase modulation on integrated o...
Multi-Point Single-Antenna Sensing Enabled by Wireless Nested Split-Ring Resonator Sensors
Ozbey, Burak; ERTÜRK, VAKUR BEHÇET; Kurç, Özgür; ALTINTAŞ, AYHAN; DEMİR, Hilmi Volkan (2016-11-01)
In this paper, simultaneous multi-point wireless sensing is proposed and demonstrated via multiple sensors in nested split-ring resonator (NSRR) geometry coupled to a single illuminator antenna. In this passive multi-point sensing system, each probe in the sensor array is assigned a non-overlapping spectral interval for frequency shift in response to local mechanical loading around a unique operating resonance frequency in the band of the antenna. Here, it is shown that the antenna is capable of capturing t...
Electromagnetic target recognition with the fused MUSIC spectrum matrix method: Applications and performance analysis for incomplete frequency data
Secmen, Mustafa; Ekmekci, Evren; Sayan, Gönül (2007-01-01)
The aim of this paper is to apply an electromagnetic target recognition method, which is based on the use of fused MUSIC spectrum matrices, to the case of incomplete frequency domain data. The aforementioned method was suggested recently and succesfully applied to both canonical and complicated targets in the presence of complete frequency domain data [1]. However, most of the real world applications involve the use of severely incomplete frequency data, especially missing low frequency information. In this...
Spatial modulation of THz beams for imaging applications
Altan, Hakan (null; 2015-10-16)
Techniques based on compressive sensing allow us to image fields at faster rates and at our labs in METU we have been experimenting with imaging based on spatial modulation of THz beams using single pixel detectors [1]. However these studies are based on discrete patterns using metal sheets. These techniques would benefit greatly if we could modulate the THz field. For example, optical modulators play a key role in optoelectronics and communication systems. Electro-optic, acousto-optic and thermo-optic effe...
Joint Utilization of Appearance and Geometry for Determining Correspondences
Soysal, Medeni; Alatan, Abdullah Aydın; Karadeniz, Talha (2009-09-16)
A novel approach, which is based on combining the competence of interest point detectors to capture primitives and the capability of geometric constraints to discriminate between spatial configurations of these primitives is presented. In the proposed approach, the geometric constraints are enforced by means of barycentric coordinates, a mathematical tool that has been utilized in the relevant literature as a neighborhood constraint. In the context of our research, however, these coordinates are utilized as...
