Tunable grating-based channel filter parking device

   
   

An optical filter, including a Bragg grating, is compression tuned such that when under one compressional load (or no load) the grating has a first profile and under a second compressional load the grating has a second profile. One application is to allow the grating filter function to be parked optically between channels of a WDM or DWDM optical system.

Un filtre optique, y compris un râpage de Bragg, est compression accordé tels que quand au-dessous de une charge de compression (ou aucune charge) que le râpage a un premier profil et sous une deuxième charge de compression le râpage a un deuxième profil. Une application doit permettre à la fonction discordante de filtre d'être garée optiquement entre les canaux d'un système optique de WDM ou de DWDM.
