Organic nonlinear optical materials are substantial in the technology era we live in, due to their applications in telecommunications, data storage, real-time target recognition, optoelectronics, and optical signal processing. The distinct intramolecular charge transfer (ICT) properties of conjugated push-pull chromophores provide high polarization and thus a strong NLO response can be obtained. NLOphores are designed to obtain more efficient and rapid NLO responses and [2+2] cycloaddition-retroelectrocyclization reaction is one of the efficient strategies to synthesize them. In this thesis, target NLOphores were synthesized via the reactions of heterocycle-substituted alkynes with TCNE and TCNQ, their linear and nonlinear optical properties were investigated using both experimental and theoretical studies.

DESIGN AND SYNTHESIS OF TRIAZENE-SUBSTITUTED PUSH-PULL DYES USING FORMAL [2+2] CYCLOADDITION RETROELECTROCYCLIZATION REACTIONS Mammadova, Flora; Dengiz, Çağatay; Department of Chemistry (2022-1-26) Conjugated push-pull chromophores are valuable due to intramolecular electron charge transfer band (ICT), second and third order nonlinear optical properties. These extraordinary features allow to use them in the area of optoelectronics where advanced applications are possible. Organic light emitting diodes (OLEDs), solar cells, organic field effect transistors (OFETs) are some examples. Synthesis of push pull chromophores is possible by click-type [2+2] cycloaddition retroelectrocyclization (CA-RE) reactio...
InGaAs nBn SWIR detector design with lattice-matched InAlGaAs barrier Uzgur, Fatih; Kocaman, Serdar (2019-01-01) Dark current optimization with band gap engineering has been numerically studied for InGaAs nBn type infrared photodetectors. Undoped InAlGaAs grading layers are utilized in constructing the barrier and dipole delta-doped layers are placed in both sides of the graded layers for eliminating valence band offset. As a result, the high band gap barrier layer blocks the majority carriers and allows minority carrier flow while minimizing various dark current components, as expected from an nBn detector. Substanti...
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...
HYBRID BEAMFORMING WITH TWO BIT RF PHASE SHIFTERS IN SINGLE GROUP MULTICASTING Demir, Özlem Tuğfe; Tuncer, Temel Engin (2016-03-25) In this paper, an efficient hybrid beamforming architecture combining analog and digital beamforming is proposed to reduce the number of radio frequency (RF) chains. It provides a good compromise between the higher degree of freedom of digital beamforming and hardware cost and complexity. In this hybrid system, two bit RF phase shifters are used as analog beamformers due to the fact that this enables the conversion of the combinatorial optimization problem to a continuous programming formulation. The overal...
Optimizing age of information on real-life TCP/IP connections through reinforcement learning Sert, Egemen; Sonmez, Canberk; Baghaee, Sajjad; Uysal, Elif (2018-07-05) Age of Information (AoI) has emerged as a performance metric capturing the freshness of data for status-update based applications ( e.g. , remote monitoring) as a more suitable alternative to classical network performance indicators such as throughput or delay. Optimizing AoI often requires distinctly novel and sometimes counter-intuitive networking policies that adapt the rate of update transmissions to the randomness in network resources. However, almost all previous work on AoI to data has been theoretic...
