Demonstrating gravitational acceleration, g≈9.77±0.01 m/s², in a Rubidium atom system using silicon photonic modulators, indicating their potential in precision measurements.
Using a high-performance suppressed-carrier silicon photonic single-sideband modulator at 1560nm, we demonstrate cold atom generation, state-selective detection, and atom interferometer fringes estimating gravitational acceleration, g≈9.77±0.01 m/s 2 , in a Rubidium atom system.
