Abstract:
Tuneable microcavity comprising:a first mirror; a second mirror positioned at one end of a mechanical structure; a piezoelectric actuator having an openingly between a first face and a second face, said first face being rigidly connected to the first mirror so that the piezoelectric actuator and the first mirror define a cavity, the bottom of which is made of the first mirror, the mechanical structure being inserted in the cavity so that the first and second mirrors are approximately parallel to each other, and a mechanical connector separable from the mechanical structure and fixed firstly to the second face of the piezoelectric actuator, and secondly to the mechanical structure to put the first and second mirrors at a predetermined distance from each other, wherein the mechanical structure comprises a support on which the second mirror is fixed and a tubular support structure with one end fixed to the support, and wherein the mechanical connector includes a plate with an orifice drilled in the plate with a diameter approximately equal to a diameter of the support structure.
