Chip-scale sub-Doppler atomic spectroscopy enabled by a metasurface integrated photonic emitter Open
We demonstrate chip-scale sub-Doppler spectroscopy in an integrated and fiber-coupled photonic-metasurface device. The device is a stack of three planar components: a photonic mode expanding grating emitter circuit with a monolithically in…
