Graphene-decorated microfiber knot as a broadband resonator for ultrahigh-repetition-rate pulse fiber lasers
Micro-resonator-based lasers have demonstrated great potential for developing ultrafast, high-repetition-rate sources with a small footprint, low cost, and little energy consumption. Reinterpreting the filter-driven four-wave mixing scheme with a peculiar all-pass configuration, Liu and co-workers demonstrated a multiwavelength source with a compact micro-knot fiber resonator featuring graphene deposition. The team demonstrates lasing over a set of frequencies spaced by the free spectral range of the micro-knot fiber resonator inserted in a laser loop with both Erbium- and Ytterbium-doped fibers, showing that this low-cost, all-fiber nonlinear device has a potential for ultra-high repetition rate sources. The results of this proof of concept are precursory for establishing the mode-locking operation of the source, and this laser configuration shows an interesting potential for pulsed operation.
