<p>A method of operational tuning of an optical structure, such as a Bragg grating, incorporated in an optical waveguide (24) mounted in a packaging device (10) is disclosed. The method comprises the steps of applying a transverse compressive load (33) to a first longitudinal member (12) of the packaging device (10), the load (33) being above a non-elastic deformation threshold of the first material member (12), to achieve a longitudinal expansion (37) of the first material member (12). The longitudinal expansion (37) results in the tuning being affected through a lever mechanism operating under relative movement of the first material member (12) and a second material member (14) of the packaging device (10).</p> |
