Claim 0:
1. An inertial sensor system, comprising:
a waveguide;
a magnetic field system adapted to establish a magnetic field gradient about the waveguide; and
a laser system adapted to emit:
a plurality of cooling beams such that the cooling beams intersect within a region in which the magnetic field gradient is formed, thereby forming a magneto-optical trap (MOT);
a red-detuned trapping beam such that red-detuned light propagates in the waveguide, the red-detuned trapping beam being red-detuned with respect to a resonant optical transition of an atom trapped in the MOT;
a blue-detuned trapping beam such that blue-detuned light propagates in the waveguide, the blue-detuned trapping beam being blue-detuned with respect to the resonant optical transition of the atom trapped in the MOT, wherein propagation of the red-detuned light and the blue-detuned light causes formation of an evanescent field optical dipole trap (EF-ODT) about the waveguide; and
a sequence of Raman pulses or a sequence of Bragg pulses, such that the sequence of Raman/Bragg pulses propagates through the waveguide wherein the sequence of Raman/Bragg pulses is adapted to impart momentum kicks to guided atoms in the EF-ODT, wherein motion of the inertial sensor system can be determined based upon motion of the guided atoms in the EF-ODT.
