We present initial measurements of an atomic magnetometer in which the microfabricated sensor head is coupled to the control system by optical fibers. Since there are no electrical connections, the sensor head is largely non-magnetic and degradation of the magnetometer performance due to internal magnetic fields is avoided. The sensor head is fabricated by use of methods derived from micro-electromechanical (MEMS) systems and integrated with off-the-shelf micro-optical components. Light is coupled through fibers to and from the sensor head for interrogation of the atoms as well as temperature stabilization of the vapor cell.
