Frequency Comb Based Multidimensional Coherent Spectroscopy

7155 – There is a large need for spectroscopic technology to be used for chemical identification. An optical spectrum can act as a fingerprint for different molecules, allowing identification, opening up the door for various applications. One area that spectroscopy has become a vital tool is the intelligence community for stand-off chemical detection (for example, detecting improvised explosive... Read More

Metamaterial Sensor Platforms for Terahertz DNA Sensing

6246 – Terahertz sensors are a promising technology for studying DNA hybridization due to the distinctive refractive response differences between single-strand and double-strand DNA polynucleotides. This inherent difference opens the door to highly sensitive label-free detection and identification of DNA sequences. A new sensing platform now promises to greatly increase the sensitivity of DNA...

Reconfigurable Mesh Filters for Broadband Terahertz/Infrared Wave Modulation

5731 – A research team at the University of Michigan has developed a terahertz (THz) modulator that exhibits broadband, high amplitude modulation index. The use of THz technologies in many industries including semiconductor metrology, food quality processing, homeland security, medical imaging and communications, has led to staggering growth in the field in the last decade. Efficient light sources... Read More

Terahertz DNA Bio-Sensor Architecture Comprising Doubly-Corrugated Spoofed Surface Plasmon Polariton Waveguide

5568 – A label-free, Mach-Zehnder interferometer (MZI) based biosensor has been developed by a research team at the University of Michigan. The biosensor has potential to detect molecular binding without the use of conventional fluorescent tags, easing preparation requirements and facilitating efficient analysis. Biosensing has become increasingly important to many industries including biodefense,... Read More

Louvered Area Detector for Radiation Spectrometers

1668-1 – UM File # 1668.1 Background In situ gamma-ray spectrometry determines the quantities of radionuclides in some source medium with a portable detector. The more established method of laboratory gamma-ray spectroscopy consists of taking small samples of the medium into the laboratory for gamma-ray analysis. In situ gamma-ray spectrometry characterizes a larger volume of material, requires less... Read More
