PROCEDIMIENTO PARA REDUCIR LA DISPERSION NODAL Y MATERIAL CROMATICA EN UNA FIBRA OPTICA DE MODOS MULTIPLES.

摘要

Modal dispersion and chromatic material dispersion in a multimode optical fiber is reduced by feeding the rays of the light beam into the end of the optical fiber the angle of each ray relative to the axis of the fiber varied in accordance with the wavelength of the ray. The shortest ray is fed at a zero angle and the longest wavelength at angle of phi max. phi max. is defined by the equation This invention relates to the reduction of both modal and chromatic material dispersion in a multimode optical fibre.
