“…It has been shown that phase-locking can occur for a large spread of microcore optical path lengths due to the lasing frequency self-tuning in the spectral gain band. Parallel coupling in the identical emitter array can be realized without losses, in contrast to experiments with linear laser array phase-locking [29,301. The difference is that there are no edge effects due to the ring arrangement of microcores.…”

The multicore fibre laser (MCFL), containing an array of singlemode microcores in a circle inside the pump core, is a promising compact laser source. The problem is to synchronize the radiation of microcores with different propagation constants at a given radiation frequency. The theory of phaselocking of an MCFL with an external mirror and an annular waveguide matched to the multicore fibre and having a length some fraction of the Talbot distance is developed. Collective mode selection appears to occur due to spatial filtering at fractional Talbot distances, while the radiation frequency selfadjusts within the spectral gain range to minimize losses. Parallel coupling between microcores is achieved in the limit of a small fill factor. The maximum number of microcores that can be coupled is found. Good agreement is achieved between the theory and previously published experimental results.

Abstract:We show a phase-locked array of three quantum cascade lasers with an integrated Talbot cavity at one side of the laser array. The coupling scheme is called diffraction coupling. By controlling the length of Talbot to be a quarter of Talbot distance (Z t /4), in-phase mode operation can be selected. The in-phase operation shows great modal stability under different injection currents, from the threshold current to the full power current. The far-field radiation pattern of the in-phase operation contains three lobes, one central maximum lobe and two side lobes. The interval between adjacent lobes is about 10.5°. The output power is about 1.5 times that of a single-ridge laser. Further studies should be taken to achieve better beam performance and reduce optical losses brought by the integrated Talbot cavity.

“…General Description of the Modal Properties of External Cavities We adopt the common coupled-mode analysis based on the calculation of the eigenmodes of the laser equation to evaluate the optical-field profiles of the N transverse modes of an array of N single-mode lasers in an external cavity, similar to the work in [12,13]. Additionally, we will take spatial filtering components inside the external cavity into account.…”

We describe the theoretical modeling of the external-cavity operation of a phase-locked array of diode lasers in two configurations, the self-imaging cavity based on the Talbot effect and the angular-filtering cavity. Complex filtering functions, such as the transmission or reflection of a volume Bragg grating (VBG), may be introduced in the external-cavity description. Experiments with high-brightness diode laser arrays were also conducted. The experimental results are carefully analyzed with regard to the numerical simulations, and the beneficial effect of the spectral selectivity of VBGs is demonstrated.
