Chip-scale sub-Doppler atomic spectroscopy enabled by a metasurface integrated photonic emitter

A Yulaev, C Ropp, J Kitching, VA Aksyuk… - Applied Physics …, 2024 - pubs.aip.org
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 …

Broadband and low-reflection mid-infrared grating coupler for a perfectly vertical fiber-chip interface

Y Wang, R Guo, C Zou, Z Zhang, K Liu, J Jiang, T Liu… - Optics Letters, 2024 - opg.optica.org
Short-wavelength mid-infrared (SWMIR) silicon photonics has gained significant attention
due to its applications in sensing, spectroscopy, and communications. A perfectly vertical …

Parabolic dielectric reflector for extreme on-chip spot-size conversion with broad bandwidth

L Moreno-Pozas, M Barona-Ruiz, R Halir… - Optics Letters, 2025 - opg.optica.org
Spot-size converters (SSCs) are key for efficient coupling of light between waveguides of
different sizes. While adiabatic tapers are well suited for small size differences, they become …
