Details
The NIST team has developed a novel approach to create lasers that can produce light at any desired wavelength, rather than being limited to specific fixed wavelengths. This is achieved by integrating the laser components directly onto a tiny integrated circuit. The researchers used a technique called heterogeneous integration, which allows them to combine different materials and components on a single chip. This enables the creation of lasers that can be tuned to emit light across a wide range of the electromagnetic spectrum, from infrared to visible light. Such versatile lasers have numerous potential applications, including optical communications, sensing, spectroscopy, and more. The ability to integrate these 'any wavelength' lasers onto compact circuits opens the door for their integration into a variety of devices and systems.
