Storing Photons: A Theoretical Possibility?

In summary, it is theoretically possible to store photons for a short period of time using a resonant cavity or crystals. However, these methods are not perfect and there is still some risk of the photons escaping. Another potential method is using a solar panel to collect and store the energy of photons, but this would not preserve the actual photons themselves.

is it theoretically possible to store photons?

maybe just for a few microseconds to begin with?

with some kind of "container" where the photon bouncing about inside. in the case of visible light maybe a container with a perfect mirror inside it?

Yes. In practice though, resonant cavities aren't "perfect", there's a significant amplitude for the photon escaping. Nonetheless it's still good enough to do some kinds of experiments.

Recent research shows promise in temporarily trapping light in crystals. Trapping light is seen as a necessary element in replacing electron storage for computer logic.

If your purpose is just to store the ENERGY of photon, then u could use a solar panel and collect the photons's light and store it in a battery. And when u want the energy again u power a matched lamp using the battery.

This won't work if u are trapping your photons and keeping them preserved.
 

Related to Storing Photons: A Theoretical Possibility?

1. How is it possible to store photons?

Photons can be stored using various methods, such as using special materials that can trap photons or using optical cavities to confine photons. These methods rely on the interaction between photons and matter, allowing for the storage of photons for a certain period of time.

2. What are the potential applications of storing photons?

The ability to store photons could have various applications, such as in quantum computing, telecommunications, and optical memory devices. It could also potentially lead to the development of faster and more efficient data storage and processing technologies.

3. Is the storage of photons a proven concept?

While there have been successful experiments in storing photons using different methods, it is still considered a theoretical possibility and more research is needed to fully understand and harness its potential. There are also challenges to overcome, such as maintaining the stored photons for longer periods of time.

4. What are the limitations of storing photons?

One of the main limitations of storing photons is the difficulty in maintaining their coherence and preventing them from interacting with their environment, which can lead to the loss of information. Additionally, the current methods of storage have limitations in terms of the number of photons that can be stored and the duration of storage.

5. How does storing photons differ from storing other forms of energy?

Storing photons is different from storing other forms of energy, such as electrical or chemical energy, as photons do not have mass and can travel at the speed of light. This means that they can be stored and manipulated using different methods, such as using mirrors or special materials, which would not work for other forms of energy.
