The ability to freeze light opens new paths for data security and sensor technology. Researchers trapped and froze a trillion-watt laser impulse into a chamber. That makes it possible to create inhomogeneous plasma. With a very high accuracy. And that is the new way to analyze plasma dynamics. But the same thing makes it possible to store data in photonic form.
And that makes it possible to create ultra-secured USB sticks.
In the same way, the system can store data in a photonic form that improves the power of the photonic computer.
The ability to store laser light and its information as a light. Makes new paths to photonics in computing. Traditional laser systems transport data to photovoltaic cells. Those photovoltaic cells transform light into binary data and then the system stores it in electric form.
When we think about things like photonic computers. The ability to store information is a very important thing. When light carries information there is a need to make sure that information isn't just destroyed. The photonic computer must have two speeds for data processing just like in human brains.
There are three types of photonic computers.
1) Photonic system there the main electric wires on the microcircuit are replaced by the laser beams and optical wires. The information between microchips travels in laser beams.
However, the microchips use electricity in their internal architecture. When a laser impulse hits the photovoltaic cells that instrument turns the light signal into an electric impulse.
2) System where data travels in the photonic form. The system uses electricity to control things like mirrors and other things like optical routers.
3) The system where the entire system lays over photonic architecture. The system can use another laser ray to control mirrors and prisms in microchips. Or the data transporter laser ray can send the power transport signal before the data transport sequence.

Theoretically, the shape of a photonic computer is not very strictly determined. There can be a light level for example let's say 10 candela that can be the border between zero and one. The 3 candela can mean that the system is shutting down and it will transport data to memory so there computer can store it for new use. The system can also use two different light frequencies or colors to transport data. For example, red can mean zero and blue can mean one.
Or the system can transport data through two lines. Line 1 can mean zero and line 2 can mean one. The system can involve serial numbers to zeros and ones that help the receiving system to sort them into the right order. This kind of system can be one kind of quantum computer. The system handles data in binary form but the extra state can determine which is the serial number of those bits for sorting them to the right row.
The first speed is fast. And the second speed is more analytic. The fast speed is for cases where the system must react fast. That thing can be that the system must warn its components if it shuts down.
Or something very important is happening. The fast information channel tells that the system must store data that it handles. So the processed data will be transferred to the data storage or the terminal to wait until the system is ready again. In photonic computers flash memory, or terminal requires the ability to store optical data.
In optical computers, mirrors, nano-crystals, and other optical systems control light beams. Those systems are not very old. The thing is that. The optical computers in the system can act as a medium between quantum- and binary computers. The optical computer transforms electric information impulses into an optical form. The optical computer is hard to make because electricity must be replaced using light.
The last version of the photonic computers is the system where the light, or optical system replaced electricity. The problem is that the measurement systems require electricity. Maybe the answer to that problem is a technology where another laser ray delivers energy to the mirror-positioning system. In the most exotic version, the same laser beam that transports data can also send energy impulses ahead of the data carrier segment.
