Fabrication of Magneto-Optical Atom Traps on a Chip

Autor: Lewis, G., Moktadir, Z., Gollasch, C., Kraft, M., Pollock, S., Ramirez-Martinez, F., Ashmore, J. P., Laliotis, A., Trupke, M., Hinds, E. A.

Ultra-cold atoms can be manipulated using microfabricated devices known as atom chips. These have significant potential for applications in sensing, metrology and quantum information processing. To date, the chips are loaded by transfer of atoms from

Publikováno v: Phys. Rev. Lett. 99, 063601 (2007)

A microfabricated Fabry-Perot optical resonator has been used for atom detection and photon production with less than 1 atom on average in the cavity mode. Our cavity design combines the intrinsic scalability of microfabrication processes with direct

Pyramidal micro-mirrors for microsystems and atom chips

Autor: Trupke, M., Ramirez-Martinez, F., Curtis, E. A., Ashmore, J. P., Eriksson, S., Hinds, E. A., Moktadir, Z., Gollasch, C., Kraft, M., Prakash, G. Vijaya, Baumberg, J. J.

Concave pyramids are created in the (100) surface of a silicon wafer by anisotropic etching in potassium hydroxide. High quality micro-mirrors are then formed by sputtering gold onto the smooth silicon (111) faces of the pyramids. These mirrors show
