This work reports the first demonstration of an on-chip atom Michelson interferometer employing a Bose-Einstein condensate (BEC). An intra-waveguide optical standing wave serves to split, reflect, and recombine the BEC while the BEC is confined and propagates in a magnetic waveguide. The combined optical beamsplitter and magnetic waveguide employed here have allowed us to study the coherence properties of matter waves confined in a microstructure.

520 $a This work reports the first demonstration of an on-chip atom Michelson interferometer employing a Bose-Einstein condensate (BEC). An intra-waveguide optical standing wave serves to split, reflect, and recombine the BEC while the BEC is confined and propagates in a magnetic waveguide. The combined optical beamsplitter and magnetic waveguide employed here have allowed us to study the coherence properties of matter waves confined in a microstructure.
520 $a To prove that the interferometer is successfully working, a differential phase shift is introduced between the two arms of the interferometer with a magnetic field gradient and alternatively with an initial condensate velocity in a trap with a longitudinal frequency of 5 Hz. We observe interference when the round-trip propagation time is relatively short, i.e., less than about 10 ms, and the maximum separation of the split wave packets is about 120 mum.
520 $a This thesis also introduces an alternative way of making a BEC by surface-induced evaporative cooling. The surface-induced cooling provides a promising technique, which can be potentially used for a continuous coherent source on the chip.
