TUNEABLE ACTIVE MICROCAVITY AND RELATED METHOD FOR MAKING SAME

摘要

The invention concerns a tuneable active microcavity and a method for making a tuneable active microcavity. The microcavity comprises a first mirror (7), a second mirror (8), and an active material layer (9). A piezoelectric actuator (12, 13) arranged outside the space located between the mirrors enables to modify the relative distance separating the two mirrors (7, 8) under the action of a control signal. The piezoelectric actuator comprises a first face rigidly connected to the first mirror and a second face rigidly connected to the second mirror such that each of the two mirrors is freely mobile under the action of the control signal applied to the piezoelectric actuator.
