Background:

Optical phased arrays (OPAs) are crucial for controlling light propagation based on the Huygens-Fresnel principle.
Coherent beam combining (CBC) enhances laser power by merging multiple sources, particularly beneficial for narrow linewidth lasers.

Purpose of the Study:

To present a novel all-fiber architecture for OPAs that enables stable phase control for coherent beam combining.
To develop an OPA system compatible with high-power continuous wave laser sources without external sampling optics.

Main Methods:

Implemented an all-fiber architecture for OPAs.
Utilized back-reflected light at fiber-air interfaces to infer and stabilize relative path length differences between lasers.
Integrated commercial 15 W fiber amplifiers for experimental validation.

Main Results:

Achieved high-power compatibility (up to 100 W per channel) with the internally sensed OPA architecture.
Demonstrated an output root-mean-square (RMS) phase stability of λ/194.
Showcased beam steering capabilities at frequencies up to 10 kHz.

Conclusions:

The presented all-fiber OPA architecture offers a robust and scalable solution for high-power coherent beam combining.
Internal phase sensing eliminates the need for complex external sampling, simplifying the system and enhancing power handling.
