The quantum cascade laser is a special kind of semiconductor laser, usually emitting in the mid- and long-wave infrared bands. Such a laser operates on laser transitions not between different electronic bands but on intersubband transitions of a semiconductor structure. Their wide tuning range and fast response time allow for faster …

The performance of digital receivers used in modern military radar, communication, and surveillance systems is often limited by the performance of the analog-to-digital converter (ADC) used to digitize the received signal. Ultrafast ADCs are critical in military applications such as military software-defined radio, radar, and electronic counter-warfare (ECW) that require …

Auxiliary ships are vital to maintaining a strong and efficient naval fleet. They are designed to perform multiple roles to effectively support combatant ships in and out of battle, as well as complete other similar naval operations. Although auxiliaries assist other ships and do not execute primary combatant operations, they …
