We investigate new classes of artificial materials exhibiting unconventional properties in order to build novel devices operating in the Terahertz regime. The design, fabrication and electromagnetic characterization of tunable meta materials with unit cells based on Split Ring Resonators are presented. By incorporation of a nematic liquid crystal in the structure, we observe a frequency shift in the resonant response over 10% in bandwidth and more than 10 dB change in the signal absorption. We discuss how such a hybrid structure can be exploited for the development of a THz spatial light modulator.

THz characterization of a metamaterial-based Spatial Light Modulator
Chikhi, N.; Lisitskiy, M.; Casini, R.; Papari, G. P.; Tkachenko, V.; Altan, Hakan; Andreone, A. (2014-05-09)

Integrated optical modulators based on photonic crystals
Gövdeli, Alperen; Kocaman, Serdar; Department of Electrical and Electronics Engineering (2018)
Photonic Crystals, artificial optical structures making manipulation of the light possible, have become a popular platform since their first development. Here, such optical components are studied theoretically and their unusual behaviors are utilized for integrated optics components. In particular, ability to change the effective index contribution of photonic crystals is exploited for the design of a low-voltage and area efficient integrated optical modulator. Variety of different aspects are compared betw...
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...
Epoxidation of olefins catalyzed by a molybdenum-Schiff base complex anchored in the pores of SBA-15
Bagherzadeh, Mojtaba; Zare, Maryam; Amini, Mojtaba; Salemnoush, Taghi; Akbayrak, Serdar; Özkar, Saim (Elsevier BV, 2014-12-01)
Novel mesostructured hybrid materials containing a molybdenum Schiff base complex grafted on the internal surface of SBA-15 pores were prepared by introducing MoO2(acac)(2) into a mesoporous silica functionalized with Schiff base ligands. The SBA-15 supports modified by an amine or salicylaldehyde were obtained by co-condensation of tetraethylorthosilicate and the corresponding organosilane in the presence of Pluronic P123 surfactant as a structure directing agent using bis[3-(trimethoxysilyl)propyl]amine o...
Sensitivity improvement strategies and applications for flexible and wearable capacitive pressure sensors
Çiçek, Melih Ögeday; Ünalan, Hüsnü Emrah; Çınar, Simge; Department of Metallurgical and Materials Engineering (2022-8)
Pressure sensors have attracted great interest in parallel with developments in wearable electronics, robotics, human-machine interface devices, and electronic skin. In this field, capacitive pressure sensors are gaining increasing research attention due to their high sensitivity, high stability, fast response/recovery times, and simple manufacturing routes. While capacitive pressure sensors have prominent features, there is still a long way to go before they become more common in wearable technology. Incre...
