The human eye can only see light at certain frequencies (called the visible spectrum), the lowest of which constitutes red light. Infrared light, which we can’t see, has an even lower frequency than ...

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 ...

Designers can now measure extremely low levels of light in low-profile applications that require surface-mount packages with the new light-to-frequency converter from Texas Advanced Optoelectronic ...
