چکیده

Atoms can be trapped and guided with electromagnetic fields, using nanofabricated structures. We describe the fundamental features of an interferometer for guided matter waves, built of two combined Y-shaped beam splitters. We find that such a device is expected to exhibit high contrast fringes even in a multimode regime, analogous to a white light interferometer.

Towards a guided atom interferometer based on a superconducting atom chip

We evaluate the realization of a novel geometry of a guided atom interferometer based on a high temperature superconducting microstructure. The interferometer type structure is obtained with a guiding potential realized by two current carrying superconducting wires in combination with a closed superconducting loop sustaining a persistent current. We present the layout and realization of our sup...

Time Reversal Method for Guided Waves with Multimode and Multipath on Corrosion Defect Detection in Wire

This study identified depths of artificial pitting corrosion on the galvanized steel wires, frequently used in bridge cables, based on the time reversal method (TRM). Specifically, the multimode longitudinal ultrasonic guided waves are excited in terms of characteristics of radical distribution of the normalized average energy flow density (NAPFD) in a wire. Furthermore, the complex defect scat...

On the Optimum Design for 1xN Multimode Interference Coupler based Beam Splitters

An analytical formula for optimum 1xN multimode input/output channel width is derived for improved performance based on the insertion loss and output uniformity. Experimental investigation of a SOI based 1x12 MMI confirms the analytical results. ©2010 Optical Society of America OCIS codes: (130.3120) Integrated optics devices; (130.2790) Guided waves

Guided wave-based pipe damage inspection by ultrasonic fiber optic sensor

Ultrasonic fiber optic sensors (UFOS) based on Mach-Zehnder (M-Z) interferometer is proposed to detect guided waves propagating in the pipe, which is common structural component in aerospace, mechanical or civil structures. The sensitivity of UFOS depends on the long sensing distance, while winding around the circumferential direction of the pipe provides arbitrary sensing length as well as sma...

Demonstration of Compact 2x2 Multimode Interference Coupler on Silicon Nanomembrane

We designed and fabricated a 2x2 tapered multimode interference coupler on silicon-oninsulator with dimensions of 12.88μm×3μm. The device keeps a 50/50 splitting ratio over a 50nm bandwidth. To our best knowledge this is the most compact 2x2 MMI demonstrated. ©2010 Optical Society of America OCIS codes: (130.3120) Integrated optics devices; (130.2790) Guided waves
