Flexible displays enable lighter-weight, lower-power, more-rugged smartphones , soldiers wearable and vehicle applications

With the flat panel display having already been widely used more than 40 years, there have been many desired changes in the display technology, focusing on developing a lighter, thinner product that was easier to carry and store. A flexible display or rollable display is an electronic visual display which …

Infrared Search and Track (IRST) emerging as preferred solution for engaging stealthy aircraft and cruise missiles

Stealth has revolutionized the Air power by vastly enhancing the penetration capabilities of fifth generation aircrafts like the F-22A Raptor developed by Lockheed Martin and Boeing, L.M. F-35 Lightning II. Stealth in military is often described to mean, all the methods, techniques and measures intended to deny or delay the …

DARPA’s LUMOS to develop Photonic integrated circuits (PICs) and photonics platforms for defence applications

Photonics is a breakthrough technology as it uses photons (smallest unit of light) as the data carrier instead of electrons (smallest unit of electricity) used in electronic ICs. As light travels at very high speeds, photonics is widely used to transfer huge amounts of data at a very high speed. …

DARPA’s NLM developing systematic approaches of designing metamaterials for imaging, AR Glasses and EMDrive.

The ability to design and fabricate materials with new functionalities opens the door to a new world of possibilities. They can be tailored to either augment the functionality of existing devices or create new devices with superior performances. EnMats are broadly defined to include, but are not limited to, metamaterials (both …

Pulsed laser deposition enabling technology for Superconductors and Nanotechnology

Pulsed laser deposition (PLD) is a physical vapor deposition (PVD) technique where a high-power pulsed laser beam is focused inside a vacuum chamber to strike a target of the material that is to be deposited. This material is vaporized from the target (in a plasma plume) which deposits it as …

Nanolasers emerging technology for  optical interconnects, near-field spectroscopy and sensing, optical probing for biological systems, microprocessors and quantum circuits

Lasers are widely used in household appliances, medicine, industry, telecommunications and more.  A nanolaser is a laser that has nanoscale dimensions. These tiny lasers can be modulated quickly and, combined with their small footprint, this makes them ideal candidates for on-chip optical computing.   Several years ago, scientists introduced nanolasers …

New efficient, high brightness, and tunable Quantum cascade laser (QCL)s technologes from mid-wave infrared (MWIR) to Terahertz region promise chemical warfare agents & hidden explosives detectors, to infrared countermeasure (IRCM) systems

Compact, chip-based lasers have conquered much of the electromagnetic spectrum, from ultraviolet to infrared, enabling technologies from digital communications and barcode readers to laser pointers and printers. Diode lasers depend on the process of electron-hole recombination: an electron from the conduction band recombines with a hole in the valence band, …

Laser stabalization and tracking technologies for moving platform mounted Directed Energy Weapons (DEWs)

The  drones have emerged as a major new threat to civilian infrastructure and military. Counter-drone technology, also known as counter-UAS, C-UAS, or counter-UAV technology, refers to systems that are used to detect and/or intercept unmanned aircraft. One of the attractive Anti-drone weapons have been directed energy weapons (DEWs) both of …

Terahertz Photonics breakthroughs promise ultrahigh speed communication systems to medical imaging and diagnostics, industrial quality control, and security screening

Terahertz (THz, 1012 Hz) technology is based on light sources with frequencies much lower than of visible light, and slightly higher than of microwaves. Such light sources have a number of unique capabilities, for example that it can propagate through most insulating materials such as paper, plastic, cardboard, clothes etc., …
