A Platform for Evanescently Trapping Rb-87 Using Silicon Nitride Strip Waveguides Buried in Silica
The work introduces a chip-scale platform to trap Rubidium-87 atoms using silicon nitride waveguides embedded in silica. By utilizing red and blue detuned optical modes, researchers created a three-dimensional, adjustable evanescent trap suitable for chip-scale quantum science experiments. This system offers potential for miniaturized applications in quantum sensing and navigation.
