Storing photons

  1. Jul 5, 2006 #1
    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.

    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.
