Photonics

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. When our eyes see a three-dimensional image such as apple, Light reflects off the surface of the apple …

Quantum key distribution (QKD), establishes highly secure keys between distant parties by using single photons to transmit each bit of the key. A unique aspect of quantum cryptography is that Heisenberg’s uncertainty principle ensures that any attempts to intercept and measure quantum transmissions, will introduce an anomalously high error rate …

Quantum cryptography is an emerging technology in which two parties may simultaneously generate shared, secret cryptographic key material using the transmission of quantum states of light. A unique aspect of quantum cryptography is that Heisenberg’s uncertainty principle ensures that if Eve attempts to intercept and measure Alice’s quantum transmissions, her …

The extraordinary promise of quantum technology—depend on quantum “entanglement,” in which the physical states of two or more objects such as atoms, photons or ions become so inextricably connected that the state of one particle can instantly influence the state of the other—no matter how far apart they are.  Entanglement links …

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 …

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 …

Flat-panel display technology is exploding on several fronts as more screens are required for more devices.  In total, the worldwide display market is expected to grow from $150 billion in 2019 to $228 billion by 2028, according to Touch Display Research. Today, the display market is dominated by two technologies—liquid …
