Improving Mid-Infrared Imaging and Sensing

Artificial optical materials could allow cheaper, flatter, more efficient detectors for night vision and other uses. A new way of taking images in the mid-infrared part of the spectrum, developed by researchers at MIT and elsewhere, could enable a wide variety of applications, including thermal imaging, biomedical sensing, and free-space communication. The mid-infrared (mid-IR) band

Dual Frequency Comb Generated on a Single Chip Using a Single Laser

Columbia Engineers are the first to miniaturize dual-frequency combs by putting two frequency comb generators on a single millimeter-sized silicon-based chip; could lead to low-cost, portable sensing and spectroscopy in the field in real-time. In a new paper published today in Science Advances, researchers under the direction of Columbia Engineering Professors Michal Lipson and Alexander

New Soft Electronic Textiles Could Offer Advanced Protection for Soldiers and Emergency Personnel

New technology that harnesses electronic signals in a smart fabric could lead to advanced hazardous-material gear that protects against toxic chemicals, according to research from Dartmouth College. In the research, the chemistry team of Katherine Mirica and Merry Smith describe the creation of new smart fabrics — named SOFT, for Self-Organized Framework on Textiles —
