By propagating beamlets from a periodically placed array of single-mode fiber amplifiers in a large mode-are (LMA) fiber, we find that a self-image of the initial beamlets is formed at certain distances in the LMA fiber. A Talbot mirror fiber device (TMFD) based on this property is proposed for phase-locking of a multi-fiber laser. For this laser system, we investigate how the LMA fiber length variation; the fiber amplifier phase variation, amplitude variation, and displacement affect the self-image qualities and the coupling efficiency.

“…Similar to Ref [18,19], we use a Talbot mirror fiber device (TMFD) which serves as an imaging resonator. The TMFD is a large mode area fiber (LMA) of a certain length with a partial reflector fabricated at one end.…”

“…A MMOF is an ideal testing bench to study the influence of doping since it is relatively simple to move the input pump beam from one core to another without changing the coupling efficiency. Thanks to recent progress in the fabrication of waveguides for coupling light in and out of MMOF [8], we envisage that our multi-spectral source based on MMOFs may provide a key component for realizing a compact SC laser array [9], or a broadband source for spatial mode multiplexed fiber optical communication systems [10].…”

“…Multicore fiber (MCF) are important for a broad range of applications spanning over the fields of telecommunication [1,2], high power fiber lasers [3,4] and medical endoscopes [5,6]. Recently there has been a growing interest for coherent beam combining [7] using MCFs both in the fields of broadband laser amplification [8,9] and lens-free endoscopy [10][11][12].…”

Single-shot polarimetry imaging of multicore fiber

We report an experimental test of single-shot polarimetry applied to the problem of real-time monitoring of the output polarization states in each core within a multicore fiber bundle. The technique uses a stress-engineered optical element together with an analyzer and provides a point spread function whose shape unambiguously reveals the polarization state of a point source. We implement this technique to monitor, simultaneously and in real time, the output polarization states of up to 180 single mode fibers cores in both conventional and polarization-maintaining fiber bundles. We demonstrate also that the technique can be used to fully characterize the polarization properties of each individual fiber core including eigen-polarization states, phase delay and diattenuation.
