A miniaturised autonomous sensor based on nanowire materials platform: the SiNAPS mote

A micro-power energy harvesting system based on core(crystalline Si)-shell(amorphous Si) nanowire solar cells together with a nanowire-modified CMOS sensing platform have been developed to be used in a...

Development of Passive Submillimeter-wave Video Imaging System

Passive submillimeter-wave imaging has been in the focus of interest as a promising technology for security applications for a number of years. It utilizes the unique optical properties of submillimeter...

Environmentally stable picosecond Yb fiber laser with low repetition rate

A SESAM-mode-locked, all-polarizationmaintaining Ytterbium fiber laser producing picosecond pulses with narrow spectral bandwidth is presented. A simple linear all-fiber cavity without dispersion compensation...

Raman Spectroscopic Insights into the Chemical Gradients within the Wound Plug of the Green Alga Caulerpa taxifolia

The invasive unicellular green macroalga Caulerpa taxifolia has spread dramatically in the Mediterranean Sea over the last decades. Its success is based on rapid plug formation after wounding, to prevent...

Beyond the realm of fluorescence

Study of Lanthanum Aluminum Silicate Glasses for Passive and Active Optical Fibers

We report on SiO2-Al2O3-La2O3 glasses – with and without Yb2O3 – suitable for nonlinear and fiber laser applications. We also present successful supercontinuum generation and fiber laser operation...

Deep-Subwavelength Plasmonic Nanoresonators Exploiting Extreme Coupling

A metal-insulator-metal (MIM) waveguide is a canonical structure used in many functional plasmonic devices. Recently, research on nanoresonantors made from finite, i.e. runcated, MIM waveguides attracted...

Analytical investigation of five Roman Pb-based scale weights (Qasr Ar-Rabbah, Jordan): A case study

The composition and corrosion behavior of five archaeological lead scale weights from Qasr Ar-Rabbah in Jordan is studied using scanning electron microscopy with energy dispersive X-ray micro-analysis...

A compact microscope setup for multimodal nonlinear imaging in clinics and its application to disease diagnostics

The past years have seen increasing interest in nonlinear optical microscopic imaging approaches for the investigation of diseases due to the method's unique capabilities of deep tissue penetration, 3D...

Modal characterization of fiber-to-fiber coupling processes

We present a detailed investigation of a fiber-to-fiber coupling process by characterizing the mode con-tent at the output of the system. In our experiment a single mode fiber is transversally scanned...
