This study presents design, analysis, optimization, and fabrication of umbrella structures as an efficient quarter wave absorber within the Long Wave Infrared (LWIR) range for uncooled IR detectors. Both the effect of the ni-chrome (NiCr) layer and effect of varying pixel pitch sizes on the IR absorption performance of the umbrella structures are examined. An average of 96% absorption is measured for the optimized case within the LWIR range.

Design, fabrication, and measurement of efficient beam-shaping reflectors for 5G mm-wave applications Karaova, Gökhan Çağlayan; Ergül, Özgür Salih; Department of Electrical and Electronics Engineering (2021-5) In this study, an optimization procedure to design corrugated passive metallic reflectors for the fifth-generation millimeter wave (5G mm-wave) applications, as well as the fabrication and measurement of the designed reflectors, are presented. Such reflecting surfaces can be used as passive repeaters in both indoor and outdoor applications to change the field coverage by redirecting incident beams into desired directions with controllable power distributions. The design procedure includes a heuristic optimi...
Development of D -type fiber optic sensors for detection of refractive index variation in evanescent wave field / Güleryüz, Burcu; Durucan, Caner; Aslan, Mustafa M.; Department of Metallurgical and Materials Engineering (2014) The purpose of this study is to design, construct, develop and test D-type multimode fiber optic (F/O) sensors based on evanescent wave field sensing. A comprehensive work has been performed both theoretically and experimentally using a geometrical modification approach to improve the sensors response in different manners for detecting the refractive index (RI) variations and bio-molecular interactions in aqueous environment. In this study, the D-type F/O sensors performance was improved utilizing optical w...
Numerical modeling and optimization of HgCdTe infrared photodetectors for thermal imaging Koçer, Hasan; Beşikci, Cengiz; Department of Electrical and Electronics Engineering (2011) This thesis presents a detailed investigation of the performance limiting factors of long wavelength infrared (LWIR) and very long wavelength infrared (VLWIR) p on n HgCdTe detectors through numerical simulations at 77 K incorporating all considerable generation-recombination mechanisms including trap assisted tunneling (TAT), Shockley-Read-Hall (SRH), Auger and radiative processes. Numerical simulations under dark and illuminated conditions were performed with different absorber layer thicknesses, material...
Numerical and Experimental Investigation into LWIR Transmission Performance of Complementary Silicon Subwavelength Antireflection Grating (SWARG) Structures Cetin, Ramazan; Akın, Tayfun (Springer Science and Business Media LLC, 2019-03-18) This paper presents a detailed comparison between the long wave infrared (LWIR) transmission performances of binary, silicon based, structurally complementary pillar and groove type antireflective gratings that can be used for wafer level vacuum packaging (WLVP) of uncooled microbolometer detectors. Both pillar and groove type gratings are designed with various topological configurations changing in various period sizes (Delta) from 1.0 mu m to 2.0 mu m, various heights/depths (h) from 0.8 mu m to 1.8 mu m,...
Design, production and performance analysis of a multi-pass matrix optical system for trace spectroscopy Önder Aksan, Tuba; Bek, Alpan; Kürüm, Ulaş; Department of Physics (2021-9-09) The design and fabrication of a multi-pass matrix optical system (MMS) for the atmospheric trace gas measurement system planned to be established is described. The measurement system is a sealed thermal vacuum-capable chamber in which synthetic atmosphere configurations can be obtained by releasing various gases into the system. To increase the sensitivity of spectroscopic measurements, a MMS is designed to extend the optical path inside the chamber. The system, which is a modified Chernin cell design consi...
