ABSTRACT:
The present invention concerns a device where the commutation of a luminous beam is ensured by the electrically controlled presence or absence, on the path of the beam, of a fluid causing said beam to be transmitted or reflected. The invention provides for improved decoupling between the output channels of the device, due to the presence of a surface provoking a total internal reflection that allows one to eliminate interference reflections.
