Abstract
There is presented a method of providing a wavelength tunable photon source (200), comprising bonding a first element (101) with a first mirror (106), a second element (102) with a second mirror (108) and a third element (103) with a photon emitter together in a structure enclosing an inner volume (214) being a sealed volume, and forming a bonding interface (212) which is gas-tight, so that the first mirror (106) is placed in the inner volume (214) so the first mirror (106) may move within the inner volume (214). The method provides a relatively simple way of obtaining a tunable photon source where the inner volume is sealed. The invention furthermore relates to a corresponding photon source, and use of such photon source.

A method of providing a wavelength tunable photon source, the method comprising
- providing a first element, comprising a first minor,
- providing a second element, comprising a second minor,
- providing a third element, comprising a photon emitter,
- placing the first element and the second element and the third element in relation to each other, so that
- i. the first minor and the second minor 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 and on a second side the third element,
- wherein
- the first minor 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 minor facing the optical cavity and where at least a portion of the inner volume, is placed on an opposite side of the first minor, and wherein an electrical, piezo-electrical, thermal or mechanical actuator is configured to move the first mirror within the inner volume.
