Measuring the modal bend loss in multimode optical fibers
We present the measurement of mode resolved bend loss in a multimode fiber. Using correlation filters the power of each mode is measured for various bending diameters of the fiber from which the bend loss...
PublicationsStructured illumination fluorescence microscopy with distorted excitations using a filtered blind-SIM algorithm
Structured illumination microscopy (SIM) is a powerful technique for obtaining super-resolved fluorescence maps of samples, but it is very sensitive to aberrations or misalignments affecting the excitation...
PublicationsEfficiency and stability enhancement of laser-crystallized polycrystalline silicon thin-film solar cells by laser firing of the absorber contacts
Polycrystalline silicon thin-film solar cells produced by continuous-wave diode-laser crystallization at the University of New South Wales were recently reported to have reached a conversion efficiency...
PublicationsMolecular pathology via infrared and Raman spectral imaging
During the last 15 years, vibrational spectroscopic methods have been developed that can be viewed as molecular pathology methods that depend on sampling the entire genome, proteome and metabolome of cells...
PublicationsFull-field dual-color 100-nm super-resolution imaging reveals organization and dynamics of mitochondrial and ER networks
Most structured illumination microscopes use a physical or synthetic grating that is projected into the sample plane to generate a periodic illumination pattern. Albeit simple and cost-effective, this...
PublicationsA miniature temperature high germanium doped PCF interferometer sensor
We report in this paper a high thermal sensitivity (78 pm/°C) modal interferometer using a very short Photonic Crystal Fiber stub with a shaped Germanium doped core. The Photonic Crystal Fiber is spliced...
PublicationsUngekühlte Thermoelement-Luftbrückenstruktur für Anwendungen im THz-Bereich
Entwickelt wurde eine Luftbrückenstruktur, auf der ein Dünnschicht-Thermoelement angeordnet ist. Dieses Thermoelement dient gleichzeitig als Abschlusswiderstand einer Antenne und als Temperatursensor....
PublicationsWound plug chemistry and morphology of two species of Caulerpa – a comparative Raman microscopy study
Caulerpa spp. form a polymer wound plug that seals their giant cells after mechanical injury to prevent fatal loss of cell material. First insights into the chemical processes underlying this rapid biopolymer...
PublicationsAccelerated life time testing of fused silica for DUV laser applications revised
We report on the continuation of a comparative study of different fused silica materials for ArF laser applications. After selecting potentially suited fused silica materials from their laser induced absorption...
PublicationsArsenic chalcogenide filled photonic crystal fibers
We prepared hybrid fibers by filling all-silica capillaries and photonic crystal fibers (PCFs) with arsenic chalcogenide glasses. The filling technology is described in detail and a theoreticalmodel for...
