Nano-opto-electro-mechanical systems (NOEMS)

Modern microelectronic semiconductors and integrated circuits provide remarkable computational and memory capabilities but lack the capability to interface with the physical world directly. MEMS (MicroElectroMechanical Systems) and the even smaller NEMS (Nano ElectroMechanical Systems)  integrate sensors and actuators on microelectronic circuitry and enabling these products, awareness of the surroundings in …

Liquid crystal on silicon (LCoS or LCOS)

Flat-panel display technology is exploding on several fronts as more screens are required for more devices. CRT still works well for screen sizes up to 40 inches. But if you want a larger screen, a flat panel TV, widescreen model or HDTV compatibility, you’ll have to choose from several types …

Infrared detectors enable Night Vision Devices, Robotic servicing mission to military missile tracking

Remote sensing is the science of acquiring information about the Earth’s surface without actually being in contact with it.  This is done by sensing and recording reflected or emitted energy and processing, analyzing, and applying that information. Some examples of remote sensing are special cameras on satellites and airplanes taking …

Thermophotonics cooling with light-emitting diodes

Thermophotonics (often abbreviated as TPX) is a concept for generating usable power from heat which shares some features of thermophotovoltaic (TPV) power generation. Thermophotonics was first publicly proposed by solar photovoltaic researcher Martin Green in 2000. However, no TPX device is known to have been demonstrated to date, apparently because …

Quantum enhanced LIDAR will help reduce environmentally damaging methane leaks from the oil and gas industry

In purely economic terms, methane leaks from well-heads and pipelines cost the oil and gas industry between $6bn and $30bn a year. In the US, methane leaks from the natural gas and petroleum industry are now the number one source of methane emissions, surpassing livestock digestion and landfill. Although it …

DARPA advances Microwave Photonics for RF signal processing and radars

The military/defense industry continues to encourage the advancement of multifunctional receivers. Yet the demands for higher-frequency operation, increased bandwidth, increased dynamic range, and enhanced sensitivity creates unique design challenges for present technology. Size, weight, power, and cost (SWAP-C) dynamics heavily influence the military/defense industry’s value for a particular technology.   …
