Quantum Cascade Laser at 120 Watts at Room Temperature

The quantum cascade laser (QCL) is based on inter-subband electron transitions inside a quantum well structure, which can be tailored to emit different wavelengths simply by changing the thickness of the constituent layers. In other words, we are no longer limited by inherent band gaps, and can demonstrate a very versatile source using one material …

Shape Shifting Antennas

The antenna consists of liquid metal injected into elastomeric microchannels. The antennas can be deformed (twisted and bent) since the mechanical properties are dictated by the elastomer and not the metal. Research from North Carolina State University is revolutionizing the field of antenna design – creating shape-shifting antennas that open the door to a host …
