Graphene and silicene quantum dots for nanomedical diagnostics
In the present work, the prominent effects of edge functionalization, size variation and base material on the structural, electronic and optical properties of diamond shaped graphene and silicene quantum...
PublicationsRemoving interference-based effects from infrared spectra – interference fringes re-revisited
Substantial refractive index mismatches between substrate and layers lead to undulating baselines, which are known as interference fringes. These fringes can be attributed to multiple reflections inside...
PublicationsBeyond Beer’s law – why the index of refraction depends (almost) linearly on concentration
Beer’s empiric law states that absorbance is linearly proportional to the concentration. Based on electromagnetic theory, an approximately linear dependence can only be confirmed for comparably weak...
PublicationsAnalysis method for detecting topological defect dark matter with a global magnetometer network
The Global Network of Optical Magnetometers for Exotic physics searches (GNOME) is a network of time-synchronized, geographically separated, optically pumped atomic magnetometers that is being used to...
PublicationsModified PCA and PLS: Towards a better classification in Raman spectroscopy–based biological applications
Raman spectra of biological samples often exhibit variations originating from changes of spectrometers, measurement conditions, and cultivation conditions. Such unwanted variations make a classification...
PublicationsMorpho-molecular ex vivo detection and grading of non-muscle-invasive bladder cancer using forward imaging probe based multimodal optical coherence tomography and Raman spectroscopy
Non-muscle-invasive bladder cancer affects millions of people worldwide, resulting in significant discomfort to the patient and potential death. Today, cystoscopy is the gold standard for bladder cancer...
PublicationsLinear and nonlinear absorption of titanium dioxide films produced by plasma-ion assisted electron beam evaporation: Modelling and experiment
Titanium dioxide films have been prepared by plasma-ion assisted electron beam evaporation. Linear optical properties have been investigated in terms of spectrophotometry while using the beta-distributed...
PublicationsA correlation study of layer growth rate, thickness uniformity, stoichiometry, and hydrogen impurity level in HfO2 thin films grown by ALD between 100 °C and 350 °C
Hafnium oxide was deposited from tetrakis(dimethylamino)hafnium (TDMAHf) and water by atomic layer deposition (ALD) on heated 4 Si wafers covered with native oxide in the temperature range from100 °C...
PublicationsBuild-up dynamics in bidirectional soliton fibre laser
Bidirectional ultrafast fibre lasers present an attractive solution, enabling the generation of two mutually coherent ultrashort pulse trains in a simple and turnkey system. Still, the lack of a comprehensive...
PublicationsResonance-induced dispersion tuning for tailoring nonsolitonic radiation via nano-films in exposed core fibers
Efficient supercontinuum generation demands for fine-tuning of the dispersion of the underlying waveguide. Resonances introduced into waveguide systems can substantially improve nonlinear dynamics in ultrafast...
