MATCHING OF WAVEGUIDE

Document Type and Number:

Japanese Patent JPS6075809

Kind Code:

A

Abstract:

1. Method of alignment of a wawe guide in respect to an optical excitation component without contact between the two elements, characterized in that one of the elements is submitted to an oscillatory movement along a closed loop in a plane transverse to the propagation axis and oscillating around a point for which the initial light intensiting injected in the wawe guide is not zero, in that the maximal value of the excitation function i. e. the maximal value of injected light intensity or a proportional part around this point is measured, in that the direction of the maximum of the excitation function is deduced from these measurements, in that the amplitude of the movement to be generated is determined, in that the instantaneous components of the gradient of said excitation function along two determined axes are obtained, and in that the mechanical means (26, 27) are brought under control for moving the other element along these axes until the components of the gradient are zero.
