Shifted Excitation Raman Difference Spectroscopy – pilot laboratory investigations for milk inspection
/en/research/research-news/shifted-excitation-raman-difference-spectroscopy-pilot-laboratory-investigations-for-milk-inspection
Raman spectroscopy can determine the chemical composition of milk. We use an in-house developed 785 nm dual-wavelength diode laser and SERDS to successfully identify major milk ingredients and…
Direct electron beam writing of silver using a β-diketonate precursor: first insights
/en/research/publications/direct-electron-beam-writing-of-silver-using-a-b-diketonate-precursor-first-insights
Direct electron beam writing is a powerful tool for fabricating complex nanostructures in a single step. The electron beam locally cleaves the molecules of an adsorbed gaseous precursor to form a…
GaAs-based photonic integrated circuit platform enabling monolithic ring-resonator-coupled lasers
/en/research/publications/gaas-based-photonic-integrated-circuit-platform-enabling-monolithic-ring-resonator-coupled-lasers
This paper reports on a monolithically integrated gallium arsenide (GaAs)-based photonic integrated circuit platform for wavelengths around 1064 nm. Enabled by spatially selective quantum well…
Double Tips for In-Plane Polarized Near-Field Microscopy and Spectroscopy
/en/research/publications/double-tips-for-in-plane-polarized-near-field-microscopy-and-spectroscopy
Near-field optical microscopy and spectroscopy provide high-resolution imaging below the diffraction limit, crucial in physics, chemistry, and biology for studying molecules, nanoparticles, and…
Miniaturized rubidium two-photon optical frequency references driven by monolithically integrated extended cavity diode laser
/en/research/research-news/miniaturized-rubidium-two-photon-optical-frequency-references-driven-by-monolithically-integrated-extended-cavity-diode-laser
We demonstrate a compact optical frequency reference using a novel 778.1 nm laser. Promising results indicate the feasibility of micro-integrating these references into matchbox-sized units for…
