A study demonstrates that graphene-based materials can be used to efficiently convert high-frequency signals into visible light, and that this mechanism is ultrafast and tunable. These outcomes open ...

Researchers have created a nanoscale structure that traps infrared light in a layer just 40 nanometers thick—over 1,000 times ...

From left to right: Schematic of the nonlinear optical mirror used for up-conversion imaging. Energy diagram showing the sum frequency generation process used for up-conversion. Representative ...

Researchers develop a highly efficient method to provide coherent light of any wavelength from visible to mid-infrared with a single tiny device. (Nanowerk News) Focused laser-like light that covers a ...

High-frequency light is useful. The higher the frequency of light, the shorter its wavelength—and the shorter the wavelength, the smaller the objects and details the light can be used to see. Extreme ...

Researchers at the Indian Institute of Science (IISc) have fabricated a device to increase or "up-convert" the frequency of short infrared light to the visible range. Up-conversion of light has ...

For high-speed and large-capacity optical communication applications and improvement of accuracy in microwave generation and evaluation equipment Results: NTT and their partners have developed a ...

The experimental setup shown here incorporates on-chip optical parametric oscillator (OPO) technology to generate a frequency comb of laser-like light covering a wide range of frequencies with very ...
