Wide adoption of Laser designators in Military to provide targeting for laser-guided bombs, missiles, or precision artillery munitions

One of the most challenging tasks in any aerial combat situation is to determine which assets on the ground should be targeted and which ones should be avoided. This is particularly challenging in the situation where enemy assets are camouflaged or hidden amongst civilian assets. Because of this a practice …

Silicon photonics and photonic integrated circuits (PICs) for Security, Defence and Aerospace

There is virtually no part of a modern defense system that is not impacted in some way by optics and photonics, even when the system is not optically based. Modern defense systems are migrating toward optically based imaging, remote sensing, communications, and weapons.   Silicon photonics uses photons to detect …

Perovskite-based LEDs are beginning to rival OLEDs in terms of efficiency

Perovskites have generated huge interest in recent years because of their potential for solid-state lighting and displays, despite lagging behind other state-of-the-art technologies in efficiency and longevity. Now two independent teams have reported light-emitting diodes (LEDs) based on perovskites that have surpassed a milestone in efficiency [Cao et al., Nature …

Countries developing Underwater LIDAR imaging systems for rapid wide-area anti-mine and anti-submarine operations

Currently, the most widely used technology to detect underwater objects  is sound navigation and ranging (SONAR), because acoustic waves can  penetrate the water depths to the bottom of the sea. SONAR also suffers from unwanted multipass echoes that are due to reflections from the surrounding terrain. Thus, high-resolution underwater imaging …

Next Generation MEMS thermopile IR sensor 2.0 for Internet of Things, smart homes, environment and energy technology

In the wake of increasing electronic gadget sales, the overheating problem for battery chargers has become an increasingly common safety issue. Overheating of chargers certainly can be caused by substandard chargers, faulty batteries, or by misuse of the chargers. In worst-case scenarios the devices melt or catch fire. Unsurprisingly, this …

Ultra-thin membrane Flexible Lasers could be used as wearable CBRN sensors, Chip spectroscopy to data-communication

Organic semiconductors enable the fabrication of a range of lightweight and mechanically flexible optoelectronic devices. Organic LEDs, solar cells, and field-effect transistors are now routinely made in bendable or even stretchable formats and with extremely low specific weights.   Most organic semiconductor lasers, however, have remained rigid and relatively bulky …
