Definitions

  • a single polarization reflection type polarization beam splitter 20 is provided.
  • the single polarization reflection type polarization beam splitter 20 reflects only light having one polarization plane out of two orthogonal polarization planes, and transmits light having the other polarization plane. Therefore, the single polarization reflection type polarizing beam splitter 20 has an entrance 20a and an exit 20b.
  • the optical path 10 is connected to the entrance 20a.
  • the guide light L11 (S) is amplified more than the guide light L5 (S).
  • the guide light L13 (S) has a higher intensity and a shorter time width than the guide light L7 (S).
  • FIG. 5 shows the internal configuration of a single-polarization reflection type polarization beam splitter having another configuration. This is referred to as a single polarization reflection type polarization beam splitter 50.
  • the single-polarization reflection type polarization beam splitter 50 has an input lens 60, an output lens 62, a birefringent prism 64, and a reflecting mirror 66.
  • the entrance lens 60 is arranged immediately after the entrance 60a. In other words, the incident lens 60 is disposed in the single polarization reflection type polarization beam splitter 50 at a position optically opposed to the dispersion compensating optical fiber 12 at the other end of the optical path 10.

Abstract

Le problème décrit par la présente invention est que des lasers à fibre, qui ont été proposés classiquement en tant que source de lumière blanche, qui est un dispositif important permettant de mesurer les caractéristiques dépendant de la longueur d'onde de fibres optiques et de composants optiques, n'offrent pas de caractéristiques suffisantes en termes de stabilité et de luminance élevées par rapport à des instruments de mesure de haute précision. L'invention concerne donc un dispositif source de lumière de sortie de fibre optique caractérisé en ce qu'il comprend : un trajet optique reliant une fibre optique d'amplification et une fibre optique de compensation de dispersion ; un réflecteur à rotation de polarisation de 90° connecté à une extrémité du trajet optique ; un diviseur de faisceau de polarisation à réflexion de polarisation unique connecté à l'autre extrémité du trajet optique ; un multiplexeur inséré dans le trajet optique ; et une source de lumière d'excitation connectée au multiplexeur. Le dispositif source de lumière de sortie de fibre optique a une stabilité d'intensité sans précédent, et offre une performance suffisante en tant que source de lumière blanche.
