Optical dipole trapping and optical tweezers have become extraordinarily interdisciplinary tools for confining and manipulating a multitude of samples, ranging from macroscopic spheres to biological structures to individual atoms. Optical lattices are an extension of optical dipole traps which provide tightly confined traps with perfectly ordered lattice spacing and controllable depth. Among atomic physicists, optical dipole trapping and its extension into optical lattices has proven useful and advantageous in numerous technological applications such as quantum sensing, metrology, timekeeping, and quantum computing.
ColdQuanta’s lattice chip is an integrated, compact, chip-scale solution capable of producing ultracold gases and 1D to 3D optical lattices. The chip contains on-chip optical elements for directing and retro-reflecting three user input beams. In addition, a glass window above the lattice provides users with optical access for through-chip high-resolution imaging of lattice-trapped atoms. The lattice chip can be incorporated in ColdQuanta’s RuBECi, miniMOT, or custom cells for your individual research needs.

An atom-chip-based integrated optical lattice system for cold and ultracold atom applications is presented. The retroreflection optics necessary for forming the lattice are bonded directly to the atom chip, enabling a compact and robust on-chip optical lattice system. After achieving Bose–Einstein condensation in a magnetic chip trap, we load atoms directly into a vertically oriented 1D optical lat- tice and demonstrate Landau–Zener tunneling. The atom chip technology presented here can be readily extended to higher dimensional optical lattices. © 2015 Optical Society of America
