Abstract
A method for balancing an integrated optical device having at least two similar arms each constituted by a light guide consists in depositing a thin metal film on at least one of the two guides, in measuring the unbalance between the light intensities transmitted by the two arms and then in adjusting the dimensions of the thin metal film in order to cancel the unbalance.
