Soliton-similariton fibre laser
(Macmillan Publishers, 2010-03-21)Rapid progress in passively mode-locked fibre lasers is currently driven by the recent discovery of new mode-locking mechanisms, namely, the self-similarly evolving pulse (similariton) and the all-normal-dispersion ... -
Influence of noise on force measurements
(The American Physical Society, 2010-04)We demonstrate how the ineluctable presence of thermal noise alters the measurement of forces acting on microscopic and nanoscopic objects. We quantify this effect exemplarily for a Brownian particle near a wall subjected ... -
Coupled plasmonic cavities on moire surfaces
(Springer, 2010-08)Surface plasmon polariton (SPP) waveguides formed by coupled plasmonic cavities on metallic Moire surfaces have been investigated both experimentally and numerically. The Moire surface, fabricated by interference lithography, ... -
Slowing surface plasmon polaritons on plasmonic coupled cavities by tuning grating grooves
(American Institute of Physics, 2010-09)We investigate slow surface plasmon polaritons (SPPs) in plasmonic waveguiding bands formed by coupled plasmonic cavities on Moiŕ surfaces. We demonstrate controlling the group velocity and dispersion of the SPPs by varying ... -
Investigation of high frequency performance limit of graphene field effect transistors
(American Institute of Physics, 2010-10)Extremely high field effect mobility together with the high surface coverage makes graphene a promising material for high frequency electronics application. We investigate the intrinsic high frequency performance limit of ... -
Localization of surface plasmon polaritons in hexagonal arrays of Moiré cavities
(AIP Publishing, 2011-01)In view of the progress on the confinement of light, we report on the dispersion characteristics of surface plasmon polaritons (SPPs) on two-dimensional Moire surfaces in the visible part of the electromagnetic spectrum. ... -
Microswimmers in patterned environments
(The Royal Society of Chemistry, 2011-07-14)Tiny self-propelled swimmers capable of autonomous navigation through complex environments provide appealing opportunities for localization, pick-up and delivery of microscopic and nanoscopic objects. Inspired by motile ... -
Direct imaging of localized surface plasmon polaritons
(Optical Society of America, 2011-08)In this Letter, we report on dark field imaging of localized surface plasmon polaritons (SPPs) in plasmonic waveguiding bands formed by plasmonic coupled cavities. We image the light scattered from SPPs in the plasmonic ... -
Fiber amplification of pulse bursts up to 20 μj pulse energy at 1 kHz repetition rate
(Optical of Society of America, 2011-08-23)We demonstrate burst-mode operation of a polarization-maintaining Yb-doped fiber amplifier. Groups of pulses with a temporal spacing of 10 ns and 1 kHz overall repetition rate are amplified to an average pulse energy of ... -
83 W, 3.1 MHz, square-shaped, 1 ns-pulsed all-fiber-integrated laser for micromachining
(Optical Society of America, 2011-08-29)We demonstrate an all-fiber-integrated laser based on off-the-shelf components producing square-shaped, 1 ns-long pulses at 1.03 mu m wavelength with 3.1 MHz repetition rate and 83 W of average power. The master-oscillator ... -
Fiber laser-microscope system for femtosecond photodisruption of biological samples
(Optical Society of America, 2012-02-22)We report on the development of a ultrafast fiber lasermicroscope system for femtosecond photodisruption of biological targets. A mode-locked Yb-fiber laser oscillator generates few-nJ pulses at 32.7 MHz repetition rate, ... -
High frequency performance of individual and arrays of single-walled carbon nanotubes
(Institute of Physics Publishing, 2012-05-28)We have studied the high frequency performance limits of single-walled carbon nanotube (SWNT) transistors in the diffusive transport regime limited by the acoustic phonon scattering. The relativistic band structure of ... -
Growth and characterization of nanocrystalline SrTiOx films: room temperature deposition using RF sputtering system in a pure argon environment
(Institute of Physics Publishing, 2017-05)We report a comprehensive description of the structure, optical and electrical properties of asdeposited and annealed SrTiOx (STO) thin films. Nanocrystalline STO films were deposited on p-type Si (1 0 0) and UV-grade fused ... -
Ethnic conflict and gender inequality in education: the case of Turkey
(Routledge, 2018-04)Although conflict remains a major obstacle to development in many areas of the world, its impact on education has been rarely studied. This article investigates the relationship between conflict and gender equality, focusing ... -
Distributed contact flip chip InGaN/GaN blue LED; comparison with conventional LEDs
(Elsevier, 2019)This paper presents high performance, GaN/InGaN-based light emitting diodes (LEDs) in three different device configurations, namely Top Emitting (TE) LED, conventional Flip Chip (FC) and Distributed Contact (DC) FC. Series ...
