Optical lattices with periodic potentials have attracted great attention inmodern optics and photonics, enabling extensive applications in atomicmanipulation, optical trapping, optical communications, imaging, sensing, etc.In the last decade, the generation of optical lattices has been widelyinvestigated by various approaches such as multi-plane-wave interferometer,beam superposition, spatial light modulators, nanophotonic circuits, etc.However, all of the previous state-of-the-art works are restricted to only oneor two dimensions of the light field, which cannot fulfill the increasingdemand on complex light manipulation. Full-dimensional and dynamic control ofthe light field, including spatial amplitude, phase and polarization, is quitechallenging and indispensable for the generation of sophisticated opticallattices. Here, we propose and demonstrate a reconfigurable integratedfull-dimensional optical lattice generator, i.e. a photonic emitting array(PEA) enabling reconfigurable and full-dimensional manipulation of opticallattices, in which 4x4 photonic emitting units (PEUs) with 64 thermo-opticmicroheaters are densely integrated on a silicon chip. By engineering each PEUprecisely with independent and complete control of optical properties ofamplitude, phase and polarization, various optical vortex lattices, cylindricalvector beam lattices, and vector vortex beam lattices can be generated andreconfigured in the far field. The demonstrated integrated optical latticegenerator paves the way for the miniaturization, full-dimensional control andenhanced flexibility of complex light manipulation.
