Alexander Graham Bell discovered photoacoustics by accident when he was working on the development of the photophone, a followup to his recently developed telephone that operated via modulated sunlight instead of electricity. You would operate a photophone by speaking into its transmitter toward a mirror placed inside of it. The vibrations …

We see things because our eyes are sophisticated light detectors: they constantly capture the light rays bouncing off nearby objects so our brain can construct an ever-changing impression of the world around us. Photography, as this became known, has revolutionized the way people see and engage with the world but …

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 …
Read More »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. …
Read More »DARPA’s DETECT developed Single photon detector (SPD) for quantum computers, communications, and submarine detection
The process of detecting light—whether with our eyes, cameras or other devices—is at the heart of a wide range of civilian and military applications, including light or laser detection and ranging (LIDAR or LADAR), photography, astronomy, quantum information processing, medical imaging, microscopy and communications, including underwater Blue-Green communications. Detection of …
