Wildfires are a growing global problem exemplified by the destruction in Los Angeles in January of this year. Photonics technologies offer some hope for early detection and mitigation using satellite-based Earth observation (EO). The application of EO to early remote detection of wildfires typically offers two key approaches. First, observers can attempt to identify chemical … Continue reading
An article by Jérémy Picot-Clémente in Laser Focus World entitled “New space race: Photonics is revolutionizing satellite networks” describes the revolution in satellite networks and related global infrastructure. A critical factor that unites the new generation of satellite constellations is the use of advanced photonics technologies to enhance inter-satellite communications, replacing radio frequency communications. From … Continue reading
A research collaboration between BoydNLOLab and Iridian Spectral Technologies has developed a novel fabrication technique for producing high-performance spectral filters in the terahertz region. The method employs metamaterials and a secret tool — double-sided tape. The image above shows a general schematic of the bilayer-metamaterial (BLMM) bandpass filter. The team achieved an entire octave-wide bandwidth … Continue reading
Raman spectroscopy is an incredibly robust tool for the identification of many classes of chemical compounds in materials. In pharmaceuticals, Raman plays an integral role in quality control and drug design. Raman is also a widely used technique in the life sciences and for process monitoring. What makes Raman spectroscopy so powerful for molecular identification … Continue reading
Quantitative polymerase chain reaction (qPCR) is a variation of the traditional PCR methodology to not just rapidly amplify and copy a DNA sample but to count how much has been produced. The amount of nucleic acid produced in a PCR experiment is highly dependent on the reaction conditions. One of the key advantages of qPCR, … Continue reading
Satellite communications (satcom) play an essential role in global communications and with an ever-increasing number of satellite networks present, satcom is likely to be responsible for greater percentages of the world’s data transmission requirements. The nature of how information is transmitted and the distances involved in satcom does pose some unique challenges for the optical components … Continue reading
