On Wednesday, July 29th, IEEE Xplore will undergo scheduled maintenance from 7:00-9:00 AM ET (11:00-13:00 UTC). During this time there may be intermittent impact on performance. We apologize for any inconvenience.
Using thinned fiber Bragg gratings coated with carbon nanotubes, we demonstrate that the reflection band can be controlled by the in-line optical power. We use the structure to realize an all-fiber tunable filter and a high optical power blocker.
