Crystals that can trap light inside them are exciting tools. If optical crystals will not conduct light away from inside them that rises their energy level until they explode. However, if the researchers can control the crystal's ability to transfer light away from inside them that makes it possible to use those crystals as data storage and invisibility systems. 

Those optical crystals can store light for quantum components. Or they can be used to store light and information for night-time use. In visions. Is possible to store light in the crystal. And then at the right moment aim it at the light detector. 

If researchers can control that process, it is possible to create new optical mass memories. For the right function. Optical mass memories require that the crystal can keep information in its form. If that light that carries information cannot stay in its original form that causes the loss of the data. There are small mirrors that can reflect 100% radiation that hits them. 

In those systems, light jumps between mirrors but the problem is that the system must freeze at a very low temperature. That removes oscillation from the system and helps to keep information in its form. The optical USB stick is like a miniature laser there are light jumps between those two mirrors. The laser writes data to that beam. And when the system needs to read that data another mirror will open. Then the beam transports that data into the photovoltaic cell. 

Those optical mass memories can revolutionize data security. The problem is how to control the reflection in the optical mass memory. And one of the answers can be those optical crystals. 

The optical crystal that traps light in it can also act as an invisibility system. The system can trap light in those crystals and then conduct it in the desired direction. That makes it possible to aim reflection and information out from the observer. Maybe in the future, those optical crystals can make those things. If those optical crystals can aim light into the aircraft's body that makes the aircraft look like a shadow.
