Because of light's intimate relationship with time in Relativity, it's more than just an appearance of stopping time. Temporally bending time around an event quite litteral stops time within the cloaked region from the perspective of an outside observer. Time is not stopped outside for the observer, and time is not stopped or slowed at all for an observer inside the cloaked region, but, as measured by someone on the outside, time most definitely stops inside the cloaked region.
To achieve spatial cloaking, the index of refraction is manipulated to slow light from a probe around an object in such a way that a "hole" in space is created, and it remains hidden [3. Alternatively, it may be desirable to cloak the occurrence of an event over a finite time period, and the idea of temporal cloaking was proposed in which the dispersion of the material is manipulated in time to produce a "time hole" in the probe beam to hide the occurrence of the event from the observer . This approach is based on accelerating and slowing down the front and rear parts, respectively, of the probe beam to create a well controlled temporal gap in which the event occurs so the probe beam is not modified in any way by the event. The probe beam is then restored to its original form by the reverse manipulation of the dispersion.

Maybe you should know what you are talking about before responding to somebody with more insane ATS gobbledygook.
The entire experiment occurred inside a fiber optics cable. Researchers passed a beam of green light down the cable, and had it move through a lens that split the light into two frequencies, one moving slowly and the other faster. As that was happening, they shot a red laser through the beams. Since the laser “shooting” occurred during a teeny, tiny time gap, it was imperceptible.
