Chip-scale sub-Doppler atomic spectroscopy enabled by a metasurface integrated photonic emitter
Alexander Yulaev, Chad Ropp, John Kitching +2
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…

Scalable and Robust Beam Shaping Using Apodized Fish-bone Grating Couplers
Chad Ropp, Dhriti Maurya, Alexander Yulaev +3
Efficient power coupling between on-chip guided and free-space optical modes requires precision spatial mode matching with apodized grating couplers. Yet, grating apodizations are…
