Paper Abstract

We investigate performance of a tiled array of adaptive photonics phase-locked elements (APPLE) or fiber collimators for (real-time) compensation of atmospheric phase aberrations. The compensation technique is based on a decoupled stochastic parallel gradient descent (D-SPGD) optimization of performance metrics. We further compare the APPLE system and the monolithic aperture adaptive optics system based on the SPGD optimization algorithm and demonstrate that the tiled fiber array is more efficient in phase aberration compensation over the large range of atmospheric turbulence strengths and under both static and dynamic turbulence conditions.
