We propose and demonstrate a loop configuration of an all-fiber acousto-optical tunable filter (AOTF). The configuration makes use of a single acoustic source to couple simultaneously flexural acoustic waves to two cascading acousto-optical (AO) sections. In comparison with conventional AOTFs, the proposed configuration greatly enhances the AO coupling efficiency and overcomes the synchronization problem in the conventional cascading configuration of AOTFs. © 2003 Society of Photo-Optical Instrumentation Engineers.
