Implication

Numerical modeling reveals optimal mode discrimination in multicore antiguided ribbon lasers, suggesting a scalable pathway for high-power single-mode fiber lasers.

Key Points

To model a scalable antiguided ribbon fiber laser architecture capable of phase locking multiple gain cores into a single spatial mode.
Designed a planar ribbon waveguide comprising alternating gain-loaded and unpumped segments with a uniform refractive index surrounded by lower-index cladding.
Conducted one-dimensional and two-dimensional optical calculations to establish design criteria and evaluate transverse mode discrimination.
Identified that maintaining a constant refractive index across the ribbon within ±0.001 is required to secure single-mode operation in a five-core array.
Demonstrated that minor periodic index variations induce a photonic bandgap, whereas the strictly uniform-index profile with periodic gain behaves as a photonic metal.
