New single-mode semiconductor laser delivers power with scalability
Berkeley engineers have created a new type of semiconductor laser that accomplishes an elusive goal in the field of optics: the ability to emit a single mode of light while maintaining the ability to scale up in size and power. It is an achievement that means size does not have to come at the expense of coherence, enabling lasers to be more powerful and to cover longer distances for many applications.

Making lasers more efficient, versatile and compact
Their inner workings reside in the realm of physics, but lasers make everyday life possible. With support from the Bakar Fellows Program, Boubacar Kante is preparing to fabricate a prototype and demonstrate the potential of the Bound State in Continuum Surface Emitting Laser (BICSEL) for a range of applications.

Light unbound: Data limits could vanish with new optical antennas
Researchers at the University of California, Berkeley, have found a new way to harness properties of light waves that can radically increase the amount of data they carry. They demonstrated the emission of discrete twisting laser beams from antennas made up of concentric rings roughly equal to the diameter of a human hair, small enough to be placed on computer chips.

Record-breaking metalens could revolutionize optical technologies
Traditional lenses — like the ones found in eyeglasses — are bulky, heavy and only focus light across a limited number of wavelengths. A new, ultrathin metalens developed by researchers at the University of California, Berkeley, uses an array of tiny, connected waveguides that resembles a fishnet to focus light at wavelengths spanning from the visible to the infrared with record-breaking efficiencies.
