We propose a new concept of a cold atom generation using a tiny optical device system. A system consists of a multi-stage nonlinear micro-ring system incorporating an add/drop filter, which the storage unit can be formed the fast tweezers and the cold atom concept presented. In operation, the optical tweezers can be generated by using a Gaussian pulse input into the microring system, where the amplified and tuned optical tweezers using a light pulse propagating within an add/drop filter. By using the suitable parameters such as ring radii, effective areas, coupling coefficients and refractive indices, an atom/particle can be trapped by the specific optical tweezers and propagating within a storage ring. Results obtained have shown that the fast tweezers time is approached the negligible value, where the terms of time independent motion of atom/particle can be performed by using the fast tweezers, and the cold atom concept is obtained. In application, such a technique can be used to form the similar manner for molecule, DNA, photon, or Ion, where the memory unit of them can be formed, which will be available for a hybrid memory or computer in the near future.
