This is rather fascinating, and certainly important if it is valid.
Using just an optical system, a group is reporting an observation of a Hawking radiation-like radiation.
To create the Hawking radiation, the scientists fired ultrashort (1-picosecond) laser pulses at transparent glass, which excited an RIP that exhibited an event horizon. Using a CCD camera, the researchers detected a peculiar kind of photon emission at a 90-degree angle to the glass. As the researchers explained, they arranged the experiment in a way to strongly suppress or eliminate other types of radiation, such as Cerenkov-like radiation, four wave mixing, self-phase modulation, Rayleigh scattering, and fluorescence.
Amazing what you can accomplish in a lab, isn't it? :)
