Harvard researchers have introduced a single metasurface that can effectively tune the different properties of laser light, including wavelength, without additional optical components. The metasurface can split light into multiple beams and control their shape and intensity in an independent, precise, and power-efficient way.
The ability to precisely control the various properties of laser light is critical to technologies that span commercial (VR) headsets to microscopic imaging for biomedical research. Many current laser systems rely on separate, rotating components to control the wavelength, shape, and power of a laser beam, making these devices bulky and difficult to maintain.
The new work from Harvard opens the door for…READ MORE
