Abstract

A tuneable active microcavity and a process for manufacturing a tuneable active microcavity. The microcavity includes a first mirror, a second mirror, and a layer of an active material. A piezoelectric actuator placed outside the space located between the first and second mirrors modifies the relative distance separating the first and second mirrors under action of a control signal. The piezoelectric actuator includes a first face rigidly connected to the first mirror and a second face rigidly connected to the second mirror such that each of the first and second mirrors is free to move under action of the control signal applied to the piezoelectric actuator.
