Not a strictly new technology but an improvement on existing concepts. This is building an artificial non-linear optic using a metamaterial to make it more compact. It works by frequency shifting the incoming infrared into the visible light spectrum without otherwise altering it. Of course it's just a proof of concept metamaterial so there's a bunch of practical limitations that will need to be overcome with engineering before it's ready for prime time.
