In order to realize the storing and releasing of electromagnetic waves, we have achieved by using an optically tunable metamaterial had a semiconductor as a mirror of a Fabry-Perot resonator. we confirmed that the released electromagnetic waves had a pulse width of about two round-trips of the resonator, and decreased exponentially with increasing storage time. In addition, we found that the storage time of the electromagnetic waves can be extended by increasing the reflectance of the mirror of the resonator.
