Photonics

Photonics, the science of generating, detecting and manipulating particles of light, forms the basis of many of the technologies we use in our everyday life. In the evolving branch of integrated photonics, increasingly large and complex optical circuits can be built on the surface of a chip. The majority of …

Navy ships face an increasing number of threats in conducting their missions, including UAVs, armed small boats, and adversary intelligence, surveillance and reconnaissance systems. The US Navy is concerned about the survivability of Navy surface ships in potential combat situations against adversaries, such as China, that are armed with large numbers …

The Laser Directed Energy Weapons (DEWs) offer a transformational ‘game changer’ to counter asymmetric and disruptive threats, while facing increasingly sophisticated traditional challenges. Laser technology provides major advantages for military applications over kinetic weapons due to High precision and rapid on-target effect, precise and scalable effects, avoidance of collateral damage …

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 …

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 …

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 …

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 …

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, …
