A WAVELENGTH TUNABLE PHOTON SOURCE WITH SEALED INNER VOLUME

摘要

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.

1. 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 thatii. 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,whereinthe 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.
