All-chalcogenide glass omnidirectional photonic band gap variable infrared filters
(AIP Publishing, 2009)We report on the design, fabrication, and characterization of spatially variable infrared photonic band gap filter that consists of thermally evaporated, high refractive indexcontrast, amorphous chalcogenide glass multilayers. ... -
Chalcogenide microresonators tailored to distinct morphologies by the shaping of glasses on silica tapers
(OSA - The Optical Society, 2017)Production of chalcogenide (As2Se3) microresonators in sphere, loop, and bottle morphologies by the shaping of glasses at appropriate temperatures between cleaved silica tapers is reported. The quality factors exceed QS = ... -
Design and implementation of capacitive micromachined ultrasonic transducers for high power
(2011)Capacitive micromachined ultrasonic transducers (CMUTs) have a strong potential to compete piezoelectric transducers in high power applications. In a CMUT, obtaining high port pressure competes with high particle velocity: ... -
Femtosecond laser fabrication of fiber based optofluidic platform for flow cytometry applications
(SPIE, 2017)Miniaturized optofluidic platforms play an important role in bio-analysis, detection and diagnostic applications. The advantages of such miniaturized devices are extremely low sample requirement, low cost development and ... -
Low-loss as-grown germanosilicate layers for optical waveguides
(A I P Publishing LLC, 2003)We report on systematic growth and characterization of low-loss germanosilicate layers for use in optical waveguide technology. The films were deposited by plasma-enhanced chemical vapor deposition technique using silane, ... -
Microsphere-Assisted Super-Resolved Mirau Digital Holographic Microscopy for Cell Identification
(OSA - The Optical Society, 2017)In this paper, we use a glass microsphere incorporated into a digital holographic microscope to increase the effective resolution of the system, aiming at precise cell identification. A Mirau interferometric objective is ... -
Nanocomposite glass coatings containing hexagonal boron nitride nanoparticles
(Pergamon Press, 2016)Glass coatings composed of SiO2-K2O-Li2O, containing non-modified and fluorosilane modified hexagonal boron nitride (hBN) nanoparticles, were prepared on stainless steel plates through sol-gel spin-coating method. Coatings ... -
Optical transitions of Tm3+ ions for amplifiers: How the local structure works in (1-Ex)TeO2 + (x)M (where M = LiCl, CdCl2, WO3) glass
(2002)Optical transitions of Tm3+ ions for amplifiers was presented. Stimulated emission cross-section at the peak wavelength of the emission bands was determined. It was concluded that Tm3+ doped binary tellurite glasses are ... -
Relationships between measured levels and subjective ratings: A case study of the food-court area in CEPA shopping center, Ankara
(SAGE, 2012-03-01)Physical comfort requirements of users; such as, thermal, visual, and acoustic comfort, should be considered and studied in detail when planning and designing public spaces. However, there is not enough research on the ... -
Tapered nanoscale chalcogenide fibers directly drawn from bulk glasses as optical couplers for high-index resonators
(OSA - The Optical Society, 2017)We report production of air-clad tapered chalcogenide fibers by directly drawing bulk glasses between cleaved tips of tapered silica fibers. Exploiting these tapered fibers with nanoscale waists as evanescent optical ... -
Terahertz Bandpass Frequency Selective Surfaces on Glass Substrates Using a Wet Micromachining Process
(Springer New York LLC, 2017)This paper presents terahertz (THz) frequency selective surfaces (FSS) implemented on glass substrate using standard microfabrication techniques. These FSS structures are designed for frequencies around 0.8 THz. A fabrication ...
