A recent breakthrough from a team of researchers has enabled ultrafast, tunable frequency conversion from high-frequency to visible light. This breakthrough could be a game-changer for many applications such as optical communications, microscopy, spectroscopy, and many more.

The research team, from the Institute of Photonic Sciences in Spain, developed a chip-integrated device that can convert infrared light with a frequency range of up to 2 THz to visible light with a tunable frequency range from 0.3 to 3 THz. This frequency conversion process is achieved by using a nonlinear optical process, which makes it possible to convert light with a frequency of up to 2 THz to visible light.

The device is powered by a femtosecond laser, meaning that the frequency conversion process occurs at a rate of hundreds of millions of cycles per second. This makes it possible to quickly and accurately tune the frequency of the output light, allowing for the conversion of high-frequency light to visible light in a matter of seconds.

The research team’s breakthrough could have far-reaching implications for many areas of technology and science. With the ability to convert high-frequency light to visible light in a tunable, ultrafast manner
