The world's first optical oscilloscope is an instrument that can measure the electric field of light. The device converts light into electrical signals, like a hospital monitor.
The electric field of light has a high speed that makes reading it difficult. The most advanced techniques, which power our phone and internet communications, can clock electric fields at up to gigahertz frequencies. Light waves allow a higher density of information to be transmitted. The current tools for measuring light fields only resolve an average signal associated with a pulse of light, not peaks and valleys. It is important to measure those peaks and valleys within a single pulse so that information can be packed and delivered.
The use of light to make things faster, but we are still functionally limited by the speed of the oscilloscope, says Michael Chini, who worked on the research at the University of Central Florida. Our optical oscilloscope may be able to increase that speed by a factor of 10,000.
The team's findings are published in a journal.
The team developed a device that could measure the electric fields of individual laser pulse in real-time. The next step is to see how far the team can push the limits of the technique.

Chini oversaw the research team and had the idea for the single-shot measurement scheme. Most of the simulations and measurements were performed by Liu. Beetar assisted with the measurement of the phase dependence. The construction of the experimental setup was assisted by Nesper and Gholam-Mirzaei. The data analysis was written by all the authors.
The single-shot measurement of few-cycle optical waveforms on a chip is described in the article. There is a DOI titled " 10.1038/s41566-021-00924-6".
Nature Photonics is a journal.
The team developed the world's first optical oscilloscope on December 13, 2021.
