Claim Text:
1. A method of providing a wavelength tunable photon source, the method comprising providing a first element, comprising a first mirror, providing a second element, comprising a second mirror, providing a third element, comprising a photon emitter, placing the first element and the second element and the third element ( i. the first mirror and the second mirror define at least a part of an optical cavity, and so that ii. the photon emitter is placed inside the optical cavity, joining at least the first element and the second element and the third element together in a coherent structure enclosing an inner volume being a sealed volume, and forming a bonding interface adjacent to the inner volume, which bonding interface is gas-tight, abutting on a first side the first element ( wherein the first mirror is placed in the inner volume so that the first mirror may move within the inner volume and where at least a portion of the inner volume is placed on a side of the first mirror facing the optical cavity and where at least a portion of the inner volume, is placed on an opposite side of the first mirror, and wherein an electrical, piezo-electrical, thermal or mechanical actuator is configured to move the first mirror within the inner volume.
