Abstract

We present a new technique for measuring the intermodal beat length of a two-mode optical fiber. We formed a Fabry–Perot fiber cavity by depositing reflective mirrors on the fiber tips. As the fiber is stretched, two series of resonance peaks are observed. One series is due to the resonance of LP<sub>01 <i>q</i></sub> modes and the other is due to the LP<sub>11 <i>q</i></sub> modes. From the separation of resonance peaks as a function of cavity length, we deduce the intermodal beat length of the fiber. The measurement principle and the experimental confirmation are discussed.
