発明の名称 (英語) OPTICAL COMMUNICATION SYSTEM
発明の概要(英語) Spatial modes emitted from a multimode optical fiber (11) are passed through a photorefractive medium (13). A guide beam having the same wave front as a signal beam having certain spatial modes, and a control beam are irradiated into the photorefractive medium (13), whereby a hologram used for signal separation is recorded. By having a control beam of a different angle of incidence for each spatial mode, a multiplexed hologram is recorded. During signal separation, a control beam (15) of a given angle is irradiated into the photorefractive medium (13), whereby the signal beam of the spatial mode corresponding to the angle of incidence of the control beam (15) is separated.
