Abstract
A controlled emission of light from an optical waveguide, e.g. a fiber into which light is injected at one end, is effected by modifying the periphery of the waveguide over a generally triangular zone so that there is a controlled emission per unit length at every point along this zone and light emanates continuously over the length of the zone from the fiber.
