A photonic integrated circuit (PIC) or integrated optical circuit is a device that integrates multiple (at least two) photonic functions and as such is similar to an electronic integrated circuit. The major difference between the two is that a photonic integrated circuit provides functions for information signals imposed on optical …
Read More »The rising cost of new weapons systems has long been a concern for the Department of Defense (DoD). And, as DoD seeks to transform itself for the 21st century, it can anticipate an extended period of downward budgetary pressure. Moreover, growing costs will require difficult choices for DoD just to …

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. Light is also being used in …
Read More »Metaverse is a vision of a highly immersive and interactive shared world inhabited by avatars of real people that will enable billions of people to work, play, collaborate and socialize in entirely new ways. As a concept, the Metaverse is a persistent, online, 3D universe that combines multiple virtual spaces. …
Read More »Although universal fault-tolerant quantum computers – with millions of physical quantum bits (or qubits) – maybe a decade or two away, quantum computing research continues apace. It has been hypothesized that quantum computers will one day revolutionize information processing across a host of military and civilian applications from pharmaceuticals discovery, …

Moreover, according to the statistical report titled “World Population Ageing 2019” published by …
Read More »The transmission loss of the light passing through the optical fiber is a very small value of less than 0.2 dB per km with a light wavelength in the 1,550 nm band. Therefore clearest optical fibers can transmit signals more than 100 kilometers without amplification-much farther than copper wires. When …

U.S. Energy Information Administration’s latest International Energy Outlook 2017 (IEO2017) projects that world energy consumption will grow by 28% between 2015 and 2040. Most of this growth is expected to come from countries that are not in the Organization …

Quantum mechanics is the fundamental theory that describes the properties of subatomic particles, atoms, molecules, molecular assemblies and possibly beyond. Quantum technology (QT) deal with practical applications of quantum mechanical properties—especially quantum entanglement, quantum superposition and quantum tunnelling—applied to quantum systems such as atoms, ions, electrons, photons, molecules or various …

Airship is a type of lighter-than-air aircraft which can navigate through the air under its own power. They are different from Aerostats that gain their lift from large gas bags filled with a lifting gas that is less dense than the surrounding air. Historically, airships have been used in applications …
