ACHROMATIC DIVIDER IN INTEGRATED OPTICS AND M INPUT COUPLER TO N OUTPUTS INCORPORATING SUCH A DIVIDER.

摘要

P The divider is produced by diffusion of ions in a glass substrate and it is designed to ensure the transmission of an optical signal to two outputs with a predetermined ratio of the powers of the signals appearing at these 2 outputs. According to the invention it comprises an X-junction of two rectilinear waveguides defining at their intersection a half-angle (alpha) between 0.7degree and a few degrees, the angle being chosen so as to establish the power ratio predetermined.
