All-Optical Logic Gates Show Promise for Optical Computing
When it comes to computing, one of the primary bottlenecks in increasing data transfer rates is the conversion time required from optics to electronics when the signal reaches a semiconductor microprocessor. One approach to addressing this problem would be converting systems to ones that are based on optics, with optical microprocessors in place of semiconductor microprocessors. Achieving this feat would lead to an era of all-optical information processing.

Germanium Alternative Gaining Momentum for IR Optics
When it comes to designing IR imaging systems, manufacturers have traditionally worked with crystalline materials such as germanium. To make compact, lightweight systems, fabricators are driven to use aspheric surfaces, which has meant diamond turning. Chalcogenide glass has emerged as another material option for IR optical elements. Not only does it boast excellent performance, but more importantly, it can be fabricated using scalable precision glass-molding methods.

Lasers Adapt to Changing Threat Landscape
Speed-of-light engagements with limited collateral damage make laser weapon systems a highly precise and scalable option in modern warfare. Lasers offer a low-cost-per-shot solution to high-volume threats posed by drones and also offer the deep magazine capability to address multiple targets with reduced logistics tails. For many years, lasers have been used in a variety of defense applications, from determining target ranges, to precisely delivering munitions, to confusing or jamming optical trackers, and as weapons to dazzle personnel or destroy targets.

Researchers have demonstrated how laser pulses emerge from noise, then collapse and oscillate before stabilizing. The discovery was made possible by real-time measurement of the laser’s temporal intensity with subpicosecond resolution and the laser’s optical spectrum with subnanometer resolution.
