Abstract

Способ изготовления одномодовых волоконных световодов, сохраняющих поляризацию излучения, путем химического парофазного осаждения внутри кварцевой трубы слоев легированной оболочки, имеющей показатель преломления, равный показателю преломления кварцевого стекла, слоев экранирующей оболочки из чистого кварцевого стекла и слоев сердцевины, последующего сплавления трубки в круглую заготовку с эллиптической легированной оболочкой и вытягивания световода, отличающийся тем, что, с целью повышения степени сохранения поляризации излучения световодов и снижения оптических потерь на ответвителях излучения за счет оптимизации профиля показателя преломления, перед и после нанесения легированной оболочки за один проход наносят компенсирующие слои, при осаждении которых в парогазовой смеси содержится вдвое меньше легирующих компонентов, чем при нанесении легированной оболочки.A method of manufacturing single-mode optical fibers retaining the polarization of radiation by chemical vapor-phase deposition of layers of a doped shell inside a quartz tube, having a refractive index equal to that of quartz glass, layers of a screen of pure quartz glass and core layers, followed by fusing the tube into a round billet with an elliptical alloyed sheath and extrusion of the fiber, characterized in that, in order to increase the degree of conservation of polarization of the radiation Ia fibers and reduce optical losses in couplers radiation by optimizing the refractive index profile before and after application of the alloy cladding applied in one pass compensating layers during deposition vapor mixture which contained half as alloying components than the substrate alloy shell.
