The Laser Directed Energy Weapons (DEWs) offer a transformational ‘ga me 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 …
Read More »Photonic Integrated Circuits technologies promise Quantum computers and sensors, as system-on-chip solutions integrated into laptops and cell phones.
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 very high speeds, photonics is widely used to transfer huge amounts of data at a very high speed. Thus …

An optical network is a communication system that uses light signals, instead of electronic ones, to send information between two or more points. The points could be computers in an office, large urban centers or even nations in the global telecommunications system. These include limited range local-area networks (LAN) or wide-area …
