Thermal stresses and cracking behavior during laser crystallization of silicon on glass for thin film solar cells
During the preparation of silicon thin film solar cells on glass substrates by diode laser induced liquid phase crys-tallization (LPC) cracking is an issue. This is due to thermal stresses caused by high...
PublikationenNonlinear refractive index study on SiO2-Al2O3-La2O3 glasses
The nonlinear refractive index n2 of SiO2-Al2O3-La2O3 (SAL) glasses of 10 to 24 mol% La2O3 is determined via Z-scan technique at 800 nm in the sub-100 fs time regime. n2 (5.8 to 9.3 × 10−16 cm2/W) correlates...
PublikationenAs2S3–silica double-nanospike waveguide for mid-infrared supercontinuum generation
A double-nanospike As2S3–silica hybrid waveguide structure is reported. The structure comprises nanotapers at input and output ends of a step-index waveguide with a subwavelength core (1 μm in diameter),...
PublikationenA semi-analytical model for the approximation of plasmonic bands in arrays of metal wires in photonic crystal fibers
We present a highly efficient semi-analytical and straightforward-to-implement model for the determination of plasmonic band edges of metallic nanowire arrays inside photonic crystal fibers. The model...
PublikationenMultimodal nonlinear imaging of atherosclerotic plaques differentiation of triglyceride and cholesterol deposits
Cardiovascular diseases in general and atherothrombosis as the most common of its individual disease entities is the leading cause of death in the developed countries. Therefore, visualization and characterization...
PublikationenTaper Device for Tolerant Coupling of Free-Space Optical Beams Into Single-Mode Fiber
A new device for improving the free-space optical monitoring and coupling into a single mode fiber is proposed. It consists of a fiber taper, which can easily be drawn from a suitable fiber with large...
PublikationenMesoporous silica particle embedded functional graphene oxide as an efficient platform for urea biosensing
The mesoporous silica particle embedded graphene oxide (GO) hybrid system is a promising platform for electrochemical biosensing owing to its large 2-dimensional structure, fast electron transfer kinetics,...
PublikationenOptical Phase Refractometer Based on Post-Processed Interferometric Tip Sensors
An interferometric tip sensor based on the postprocess of a special design double-cladding optical fiber is proposed. Due to the sensing head design, it is sensitive to environmental variations. In order...
PublikationenFiber Bragg Gratings in the Visible Spectral Range With Ultraviolet Femtosecond Laser Inscription
In this letter, we investigate the inscription of fiber Bragg gratings in the visible spectral range using deep ultraviolet femtosecond laser exposure and two-beam interferometry. The properties of first-order...
PublikationenClassification and prediction of HCC tissues by Raman imaging with identification of fatty acids as potential lipid biomarkers
Purpose Patients with hepatocellular carcinoma (HCC) can only be treated curatively at early stages and then have a favorable prognosis of this often fatal disease. For this reason, an early detection...
