Abstract:
A method for compensating for the existing stress induced in an optical component housed in a holder which is secured to a wall of an optical module, the method comprising the steps of:(a) measuring the initial effect of the existing stress induced in the optical component;(b) applying a compensating force along the circumferential surface of the holder and at a distance from where the holder is secured to the wall of the optical module for transmitting a radial component of the compensating force to the optical component so as to counteract the existing stress induced in the optical component;(c) measuring and recording the current effect of the existing stress induced in the optical component; and(d) applying compensating forces each positioned radially offset from the last compensating force if the current effect of the induced stress is less than the last recorded value by a predetermined amount.
