OPTICAL DEVICE CONTAINING A FIBRE-OPTIC COMPONENT

摘要

An optical device is described, comprising a fibre-optic component, such as a fibre grating, which is associated with a predetermined transfer function, capable of being placed in a plurality of adjacent windings. Furthermore, th e optical device is provided with a rigid housing capable of containing the sa id fibre-optic component, characterized in that it contains at least one separating element for physically separating the windings of the said plurality so as to prevent mutual contact through superposition and an eleme nt for fixing the said fibre-optic component capable of holding the said component in a stable position. The solution makes it possible to avoid undesirable changes of the transfer function that can occur during placement of the fibre-optic component in the housing and/or during the life of the device.
