The world population is estimated to reach 9.8 billion by 2050. Ensuring an adequate food supply for such a large number of people would be challenging enough for agriculture. But climate change is putting even more pressure on farmers, agricultural companies, and crop scientists to protect plants from the effects …

Optoelectronic technology is a new technology formed by the combination of photon technology and electronic technology. Optoelectronics is the field of technology concerned with electronic device application to the sourcing, detection and control of light. Optoelectronics is  described as “a device that responds to optical power, emits or modifies optical …

A classical lens made of plastic or glass has a curved shape that bends the path of incoming light toward a single focal point on a piece of photographic film or an electronic sensor. This is because light travels faster through the thinner glass at the edges of the lens …

An event camera, also known as a neuromorphic camera, silicon retina or dynamic vision sensor, is an imaging sensor that responds to local changes in brightness.  Event cameras do not capture images using a shutter as conventional cameras do. Instead, each pixel inside an event camera operates independently and asynchronously, …

Night vision devices are becoming essential equipment for night driving, night flying and night surveillance, wildlife observation and search and rescue missions. According to Industry ARC’s report on Night vision devices, the market is estimated to grow to $20.5 billion in 2020 at a CAGR of 7%.   Since the …

Optical communications make use of light waves, very high frequency (100 terahertz) electromagnetic waves, for information transmission. Modern optical communications were begun in the 1960s, when lasers were invented as a coherent light source. Since then, the rapid development of photonic technologies has made possible optical communication links with a …

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 …
