Approximately 80% of the matter in the universe is predicted to be so-called "dark matter," which does not emit, reflect, or absorb light and thus cannot be directly detected using conventional experimental techniques.
A study published in Opto-Electronic Science discusses high-intensity spatial-mode steerable frequency up-converter toward on-chip integration.
