英文摘要：

Laser induced spin-orbit couplings on ultra-cold atoms offer an effective platform to study various quantum physics phenomenon. We proposed and experimentally realized a two dimensional spin-orbit couplings with optical lattice for 87 Rb, together with its topological band structure. With the scheme,there is no need for phase locking and fine tuning for optical potentials. The System can be controlled to transfer from one dimensional to two dimensional. We studied the transfer process, spin-orbit coupling effect and non-trivial topological band phenomenon. Because the system has a small heating effect and is topologically stable, our scheme opens a broad prospect for using cold atoms to study exotic quantum phase .such as topological superfluid.
