Claim 18:
19. An inertial sensor system, comprising:
a substrate having an opening formed therein;
a membrane that extends across at least a portion of the opening formed in the substrate;
a waveguide that is deposited on the membrane such that the waveguide is suspended over the opening in the substrate;
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 pulses that are 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.
