発明の名称 (英語) MODE MULTIPLEXER
発明の概要(英語) A mode multiplexer wherein a rectangular waveguide that performs separation by removing the degeneration of a TE01 mode and a TE10 mode and the degeneration of a TM01 mode and a TM10 mode. An asymmetrical taper-coupling mode-transitioning waveguide that is formed from a multimode waveguide and a single-mode waveguide is used to perform mode conversion between a higher-order mode of the multimode waveguide and a fundamental mode of the single-mode waveguide by means of an adiabatic mode interaction. The magnitude correlation between the propagation constant of the higher-order mode of the multi-mode waveguide and the propagation constant of the fundamental mode of the single-mode waveguide is interchanged along the direction of propagation, and, as a result of the optical power switch that occurs because of the interchange of the propagation constants, degeneration of the higher-order mode is removed or a degenerate higher-order mode is generated. When degeneration of the higher-order mode is removed, degenerate primary TE and TM modes are separated by a square waveguide into a substrate-parallel-direction higher-order mode and a substrate-perpendicular-direction higher-order mode.
