Electrooptic switch with asymmetrical directional couplers

Not Accessible

Your library or personal account may give you access

Abstract

Electrooptically tunable directional couplers driven by varying the voltages at their electrodes are used as switching elements for conventional integrated- optic switching arrays. The low limits for the crosstalk of the elements require an Individual control of every switching voltage due to the tolerances in wavelength, production conditions, and temperature.
