Shifted excitation Raman difference spectroscopy identifies soil minerals and predicts soil carbonate content SERDS using 785 nm dual-wavelength diode lasers is a powerful technique for soil inspection under the influence of strong fluorescence interference. This could help to improve crop productivity as well as soil health and to reduce fertilizer usage. FBH research: 06.02.2023
Compact single-stage 90 GHz power amplifier for terahertz applications We have realized a compact power amplifier using our InP MMIC process, achieving a maximum output power of 12.5 dBm with 17% efficiency. The circuit is equipped with low-temperature indium bumps for flip-chip mounting. FBH research: 23.01.2023
New Focused Ion Beam System for Device Characterization and Rapid Prototyping FBH recently installed a Helios 5 UX dual beam system that combines a focused gallium ion beam with a scanning electron microscope. The instrument will be used for microscopic analysis of materials and devices as well as for rapid prototyping of nano-optical components. FBH research: 09.01.2023
