(JA) 光通信システムおよび光通信方法
Abstract:
(EN) The objective of the present invention is to bring out the potential capabilities of mode-division multiplexing (MDM). This optical communication system is provided with a hologram medium (1) in which holograms are multiplex-recorded to correspond to each spatial mode of a signal beam transmitted by a multi-mode fiber (MMF) (2). A phase plate (4) which modulates the phase of each spatial mode to reduce the spatial overlap of each spatial mode is disposed on the side of the hologram medium (1) on which the signal beam is incident.
(FR) La présente invention vise à exploiter les capacités potentielles d'un multiplexage par répartition en mode (MDM). Un système de communication optique selon l'invention comprend un support d'hologramme (1) dans lequel des hologrammes sont enregistré en multiplex de sorte à correspondre à chaque mode spatial d'un faisceau de signal transmis par une fibre multimode (MMF) (2). Une plaque de phase (4) qui module la phase de chaque mode spatial pour réduire la superposition spatiale de chaque mode spatial est placée sur le côté du support d'hologramme (1) sur lequel le faisceau de signal est incident.
(JA) MDMの潜在的な能力を引き出す。光通信システムは、MMF(2)によって伝送される信号光の各空間モードに対応してホログラムが多重記録されるホログラム媒質(1)を備えており、上記ホログラム媒質(1)における信号光の入射側に、各空間モードの位相を変調し、各空間モードの空間的な重なりを小さくする位相板(4)が配置されている。
