摘要： A laser beam with an annular or ring shaped intensity distribution, such as a TEM01* beam, is scanned across the surface of a photosensitive thin film to directly produce changes of refractive index in selected regions of the film. This method is suitable for producing channel waveguides for planar lightwave circuits, where the refractive index profile (solid curve) of such a waveguide is more uniform than the prior art refractive index profile (dashed curve) produced by a TEM00 laser beam, and has a reduced bend loss.

摘要： Process for commanding a remote video processing chain producing a video stream transmitted to a terminal with a view to acting on the transmitted video stream, this process including steps in which the terminal transmits a command to the remote video processing chain to modify the transmitted video stream, and the video processing chain executes the command on the video stream before transmitting it to the terminal. The video stream processing commands that can be performed by the video processing chain include commands that contain the definition of an image region of the image contained in the transmitted video stream and associated with the definition of processing to be applied to the image region.
