Title:
空間多重化のためのステップインデックス・少数モード・ファイバ設計
Document Type and Number:
Japanese Patent JP2014509411
Kind Code:
A
Abstract:
In an optical fiber, a plurality of individual cores extend through a common cladding. Each individual core supports at least one local transverse spatial mode. The individual cores and surrounding cladding are structured to support propagation of plurality of desired signal-carrying modes, while suppressing undesired modes, thereby supporting the propagation of one or more spatially multiplexed signals. The core-to-core spacing of the fiber is configured to maintain an acceptably low level of mode-coupling between cores.
