Kavli Affiliate: Long Zhang | First 5 Authors: Tinghui An, Tinghui An, , , | Summary: We report a mid-infrared ring laser via fiber-to-waveguide hybrid integration enabled by directional couplers fabricated in fluoride glasses. Directional couplers were inscribed into fluoride glass using femtosecond laser direct writing, forming low-loss waveguides with a high positive refractive index […]
