How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...
Researchers have miniaturized a spectrophotometer onto a single chip that can analyze any wavelength of visible light and part of the infrared spectrum (Science 2021, DOI: 10.1126/science.add8544).
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 ...
